Properties and characteristics of sleeping bags

Before purchasing a sleeping bag, you should carefully examine all the characteristics. Going on a trip, you are trying to find ways to minimize the weight of equipment. You need to achieve maximum comfort at a minimum weight. In other words, the lower the temperature, the bigger the baggage.

Select a sleeping bag from the abundance of the existing market, not very easy. Before you start looking for the right sleeping bag, you need to understand the technology and terminology. Look for which conditions are issued sleeping bags. The correct definition of the operating conditions affect: weight, comfort, price (appropriate price for target you choose), and of course for a healthy and restful sleep. Sleeping bags to destination can be divided into 3 types:
1) Extreme sleeping bags is designed for use in extreme weather conditions (low temperatures, high humidity or hot climate and soD.) Are used by sportsmen, tourists. As a rule have the shape of a cocoon. The cocoon is the most teplosberegayuschaya design. The most used and the most modern technologies: membrane fabric, various types of fillers down and synthetic fibers! With all the technological are light weight and size (when folded). The most expensive of all types of sleeping bags! Extreme sleeping bags may not differ special comfort, the emphasis has been on reducing the volume, weight, minimization of heat losses! Because extreme sports and tourism involve carrying gear for yourself! Comfort temperature 0 degrees or below. Extreme temperatures can reach -60C.
2) Tracking sleeping bags is the most accessible and popular sleeping bags. The purpose of the wide ranging from simple hikes to long multi-day hikes. Available in different forms: cocoon, blanket with hood, blanket. Fillers most often used synthetic fibers, less fluff. Have the most optimal combination of price/quality. Manufactured with an emphasis on comfort. Therefore, have a greater weight and volume relative to extreme sleeping bags. The comfort temperature of sleeping bags up to 0 5 degrees.
3) Camping sleeping bags – the most simple and affordable sleeping bags. The most comfortable and spacious. Comes in the form of blankets or blankets with a hood. The filler is usually synthetic. Designed for operation in temperate climates, in the warmer months. Rare to find a model with a comfort temperature below +5 degrees.
Size of sleeping bagWhen choosing a sleeping bag size should be given special attention. Not to carry the extra weight and save space in your backpack. Sleeping bags are unisex, ladies and kids. The difference lies in the cut of the sleeping bag and its length. Each manufacturer has its own marking dimensions of sleeping bags. In the passport or on the cover of a sleeping bag, must be specified the size of the sleeping bag to see

Unisex 84х190 see (a standard sleeping bag) is designed for a person of average complexion and height.

Female 73х170 see – narrower in the shoulders and less in length. Despite the fact that sleeping bags are stitched with size and cut for the female figure, they are suitable the men below average height and great physique! Have little advantage over standard sleeping bags in weight and size (Packed). The more compact dimensions allow you to avoid unnecessary heat loss!
Baby 71х145 see (or less) – available in fun colors and patterns. Have a great rear pocket which can fit a Mat. In order for the child during sleep was off the Mat. Some models use Velcro or straps to fix the rug.
Increased 96х205 cm (and longer) – for tall men available increased, they are longer and wider. Quality sleeping bags to package completed with a compression bag that allows to reduce the dimensions of the folded sleeping bag 1.5-2 times.
Compression sack can be bought separately. Can be used to compress the fleece jackets, etc. things! Significantly helps to free up space in the backpack for equipment needed in the campaign.

Packing size

On the package of a sleeping bag or in your passport indicate the size of a sleeping bag in packages of 40(33)х23. Where 40 is the length in cm. and 23 is the diameter in cm. The size in parentheses indicates that the sleeping bag can be reduced in size 33х23 cm for a short period of time. It is a short period of time from a prolonged stay in highly compressed state of the filler (insulation) loses its properties!

Susceptibility to cold

Susceptibility to cold in different people and age groups. The most susceptible to cold are considered to be people with a slow metabolism. High susceptibility to cold differ women, children and the elderly. Minimum temperature in the 5C. lower than normal healthy person. When choosing a sleeping bag should not forget about it. What I meant to say: when choosing a sleeping bag with a comfort temperature of +10 degrees and under the condition that you think the article is it is best to take with the comfort temperature +5 degrees!

Temperature standard

Until recently there was no generally accepted standards for testing sleeping bags. A group of European manufacturers of outdoor products was developed by standard EN13537 temperature and passed in 2002. In 2005. January 1 came into force amendments to the EN13537 standard. According to which all sleeping bags manufactured by standard EN13537 temperature should undergo laboratory testing, all samples passed the tests and meet the requirements of the standard are marked by a sign (CE).

Temperature marking

Temperature marking indicates the ambient air temperature around the sleeping bag in a tent or outdoors. Has 3 values: comfort, min. comfort, extreme.
Comfort – the temperature at which you'll feel comfortable in the sleeping bag. Can have the values positive(+5C), if it's a summer sleeping bag or negative (-2C, -5C). When choosing sleeping bags are targeting on this value on the temperature markings. If you have increased susceptibility to cold, it is best to buy a sleeping bag with a stock 5-10S towards the cold. For people with increased susceptibility to cold, it is recommended to use underwear!
Minimal comfort is the temperature at which you will feel uncomfortable in the sleeping bag. Still, this is the temperature indicated as the temperature to which it is recommended to use a sleeping bag without harm to recreation and the health consequences!
Extreme is the temperature at which you will be able to survive in the sleeping bag. Temperature limit for use of a sleeping bag. The manufacturer cannot guarantee whether there will be implications for your health, because it depends on individual tolerance (susceptibility) to cold. To navigate to this temperature when choosing a sleeping bag should never. Because following all the standards, a sleeping bag at this temperature, should provide its owner for at least 6 hours good sleep, without lowering the body temperature to critical values! From my personal experience and experience of seasoned travelers know: if a down sleeping bag is this marking comfort -2, min. comfort -9C, extreme-28C. At t-2C you will be basking in the sleeping bag without noticing that it's getting colder, and in the -9C to sleep you will be able to work and have to dress up warmly! What if we declared-28C can yourself imagine!

Insulation-the filling (down or synthetic)

as a filler (insulating material) used fluff or synthetic fibers (synthetic fiber). The most expensive and high quality are considered to be sleeping with Pooh, but Pooh has several disadvantages. Sleeping bags with synthetic filling are considered cheaper and more available. It is worth noting synthetic fillers are not all CHEAP, the most technologically not far behind in quality and price from feather fillers. Therefore, the most technologically advanced models with synthetic filling, can exceed in value even the most expensive down, but this is more the exception than the rule. Now in order start with feather fillers, its advantages and disadvantages.



The warmest and lightest of all the fillers sleeping bags. Sleeping bags with a down filler more compact when folded than synthetic. The main drawback of down its hygroscopicity (ability to absorb moisture). Moreover, we note that in field conditions drying, this sleeping bag is NOT POSSIBLE. Producers are actively fighting for freedom from this drawback! By applying the waterproof treatment of down trains.
Pooh is different, or rather 2 types:
1) Eider ideal filler for the duvet of a sleeping bag (the most expensive of feather fillers, very rare)
2) Goose more affordable and most common.
Down the filler consists of not only Pooh, Pooh add pen. The pen is added to prevent caking down. The more pen the colder a sleeping bag. Branded sleeping bags the ratio of fluff/feather is 80/20%, ideally 90/10%. Pooh has a measure of elasticity (ability to return to initial volume after compression) is denoted as FP (fill power). The maximum value that can be found today, 800 FP, a normal term is the value of FP 550. Down sleeping bags are used for mountaineering and winter Hiking. It is not recommended to use down sleeping bags in climatic zones with high humidity! Modern brand sleeping bag with a feather-filled with proper care and storage will last more than 1 and 2 years, and up to 10 years.
Pooh
+ the exceptional ratio of insulation/weight
+ excellent compressibility
+ excellent moisture removal
+ the long duration of use without loss of properties
+ warms quickly
is not warm when wet
- requires careful maintenance
- absorbs moisture
- long drying time

Synthetic

Sleeping bags with synthetic fillings are gaining popularity. Synthetic fillers are more versatile, resistant to moisture, resistant to bacteria and mold. The main advantages of synthetic sleeping bags, the possibility of drying in the field, and they warm even wet! The downside is bulk and weight (more than down). Sleeping bags with synthetic filling is cheaper than down (in any rule there are exceptions). Synthetic filler is a hollow long fibers with one or more channels in the core. The more channels you have, the easier the material and the sleeping bag accordingly! Synthetic fillers can be divided into groups: expensive (high-tech), medium price range and budget.
high-Tech synthetic fillers
high-Tech fillers closer just got to feather the filler in quality. Fillers are used in extreme sleeping bags with temperatures of max to 25 and 30°C. They are small, relatively light weight, high resistance to compression and, unlike down is not practically wet. The most high-tech fillers are: Thinsulate (3M), Polarguard (Dupont), Supreme Powerfill, Micro-loft, Termolite Extreme.
Fillers of an average price categoryMore affordable heaters: Hollofil, QualoFill, Thermoloft, Warmloft, Powerfill Soft. Apply to sleeping bags with temperature extreme max -20-25°C.

Cheap fillers

To the inexpensive fillers are sintepona and holofiber, sleeping bags with filler suitable for use only in the summer to 0°C. The experience of users of sleeping bags with these fillers, they are not durable and quickly lose their properties especially after washings!
And when you buy should pay attention to where they were made filler! Cheap Chinese filler guarantees absolutely nothing! Be careful when choosing and buying!
SYNTHETIC
+ retains 70% of the warming properties while wet
+ absorbs little moisture

- heavier duvet filler
- less compressibility
- less discharge of water
- shorter life expectancies than fluff
- longer warms
Fabric sleeping bags
For the manufacture of sleeping bags use synthetic (Nylon, Polyester) blended fabrics and Cotton 40S fabric with impregnation. The most common fabric for sleeping bags have been Nylon (nylon) it is modified, and Polyester . In sleeping bags with synthetic filling are used wicking breathable fabric (membrane tissue), such as: GORE-TEX, ComfortTex, SimpaTex. For down-filled sleeping bags manufacturers have developed special fabrics that hold the fluff. Pertex, Ultrex, etc. In Deuter sleeping bags in cold areas of a sleeping bag, for example in the legs, doing inserts of fleece fabric. Such insertions can often be found on a sleeping bag intended for children or female models. Camping in the models of sleeping bags, back doing synthetic fabric, and the inner from cotton fabrics (blended). Which gives the sleeping bag the comfort and comfort of your blankets! Fabrics in which the impregnation is applied PU (polyurethane) are the worst and short-lived option! The fabric is not breathable and does not remove moisture, the sleeping bag of this fabric inside sweat!

the little Things that create comfort

Choosing a sleeping bag, pay attention to the following details:
hood should have couplers with locking mechanism (to reduce heat loss, and ease of fitting)
Collar. Sleeping bags with collar must have couplers with clamps (extra comfort, reducing heat loss)
lightning protection of summer or sling (to prevent biting zipper) sewn along the entire length of the zipper
double-sided lock (for ease of fastening with zip inside)
valve insulating tape from the inside of a sleeping bag. Must be sewn along entire length of zipper to reduce heat loss.
inner pocket is designed to store the individual medicine or pillows
pocket for Mat for kids has a pocket for Mat ,the caremat or samolazovskoe Mat
Compatible. Some models of sleeping bags can be sostenuti, these sleeping bags are available with left and right zipper (instructions are usually listed)
loop for drying and storage (sewn on the outside at the bottom of a sleeping bag!)
the Seams – insulation must be stitched in several places (to prevent it from spreading and the formation of cold zones)
locking mechanism to prevent unzipping (Velcro prevent unzipping while you sleep!)
Guidelines for using the sleeping bag
waterproof bag – dry gear the key to your health and comfortable sleep. In order to avoid wetting of equipment you can use the dry sack. Available in different volumes are not expensive from 500 to 1500 rubles.
Pad – caremat or self-inflating Mat is recommended to reduce heat loss.
Protection from wind - wind leads to blowing heat from the sleeping bag and reduce its warming properties. Try to find protection from the wind, use a tent. If you prefer to sleep outdoors, place the sleeping bag so that it minimally abdualla wind!
Clothes – dry clothes reduces heat loss, use the underwear with the well received. Knitted or fleece hat will help to reduce heat loss and make your sleep more comfortable! In down sleeping bags type a cocoon and sleeping bags with a hood you can not use a hat! The hood is pretty tight to the face and is able to protect you from the cold cold evenings and morning.
Insert for sleeping bag Liners are made of cotton or artificial silk. The use of the liner allows to increase the removal of moisture from the body, to reduce heat loss, keep the sleeping bag clean, much longer. Increasing the interval between washings. Accordingly, increasing the lifetime of a sleeping bag! Using the liner makes the sleeping bag warmer!

Storage, transportation, Babysitting

Buying a sleeping bag, always want to it last if not forever, at least longer. At observance of all conditions of operation and storage lifetime: down sleeping bag reaches 10 years, a synthetic 5-7years (given the terms of the indicative and depend on frequency of use)! What do I need? Recommendations for storage, handling and transportation for down and synthetic sleeping bags are the same!

Storage

Stored sleeping bag needs in the expanded form in the cotton bag (a bag for storage, usually attached to the sleeping bag) if bag is missing can be purchased separately or be used as bag a big pillow! Ideal for storing a sleeping bag is the storage of a sleeping bag in a suspended condition.
After using the sleeping bag should be turned inside out and dried in limbo. 2 days to dry enough!
do Not store the sleeping bag in compression sack (entails-caking agents filler, loss, fluffiness ).

Care

it May happen that after prolonged use sleeping bag is dirty or has a bad smell! To wash sleeping bag preferably manually! Squeeze the sleeping bag is impossible! To be dry-cleaned undesirable. Only in extreme cases and with instruction,delicate wash,,! Follow the manufacturer's recommendations for Laundry products! Sleeping bags with a membrane or impregnation (waterproof ,,PU,,) as the rule type (saturate) a lot of water when washing. Therefore, to treat them in the wash carefully to avoid damage to the seams!
Many ask if I am travelling from early spring to late autumn, how many sleeping bags do you need? Experience shows optimally 2pcs one SUMMER: cheap, but quality (brand). Second SEASON best meets your desire to knock or not to knock teeth from the cold of the night or in the morning! Not necessarily expensive! You need to be oriented to the COMFORT temperature -2-7 C. If you choose down sleeping bags, prepare for a very thorough care and preservation of your sleeping bag even with the slightest wet! I never heard bad reviews about sleeping bags from tourists who've spent the money on a good off-season or winter sleeping bag!

Now, armed with the theoretical data, we give examples of specific models for specific tasks:

Propose the following objectives: - why the need for a sleeping bag:

1) For summer trips, weekend outings, fishing, camping (staying in a camp in nature), simple weekend trips. Volume, weight and comfort at low temperatures (less than +5) doesn't matter.

2) For a summer of long hikes with heavy gear or Cycling trips on flat terrain. In such campaigns actually no extreme temperatures, temperatures always above +5. Important weight and volume of a sleeping bag.

3) For a summer of long hikes in the mountains. Important weight, volume and comfort in near zero temperatures at night.

4) For fall and spring departures on weekends, fishing, hunting. Not important weight and volume, but the comfort at temperatures close to zero.

5) For the autumn and spring long hikes. Value comfort at temperatures close to zero, but also the weight and volume.

6) For winter hikes (unlikely those who travel just to take a walk on the weekend, will spend the night in the winter forest,). First of all the comfort at temperatures below zero, and then volume and weight.

For summer trips for the weekend when you don't need to lug a catamaran or a climbing iron, you can use any sleeping bag from holofiber and the like. If no extra money, and to fake it not to anyone, then go to any sportmagazin to buy some of these salnick. If the night temperature does not fall below + 10 degrees, then you will not freeze. Of course, it is necessary to understand that such sleeping bags in a couple of years istonchaetsja, material is matted, and the sleeping bag stops heat, even at + 10.

If you go in summer long trips on flat terrain, which have to lug around a bunch Tyulenovo equipment, for example, summer alloys, sailing and Hiking tours, there are not going to think about the weight and volume of a sleeping bag. Of course, best sleeping bags of Thermolite Extreme or Polarguard, but it's a price.

summer Hiking in the mountains need to abandon the simple Holofiber. After all these tasks are very important comfort at temperatures close to zero, which means that the sleeping bag from HF will weigh 2 pounds. So here we have again to choose between saving money or saving weight, that is to buy a sleeping bag from medium weight fillers, 1400 – 1700 g or pay more and get a significant gain in weight and volume in the sleeping bags of high quality modern fillers.

fall and spring trips for the weekend, fishing, hunting could be limited from Hollowfiber sleeping bag weighing about 2 pounds.

If you are going in sports for a long period in the fall or spring, here in any case, you need to understand that and be in the mountains and on the plain at night will be cold, so the comfort temperature should be in the range of 0 /-5. It is unlikely you will want to lug a 2.5 pound sleeping bag from HF, so you need to be prepared for expenses. Oh, and then it's up to you. We must not forget that besides weight, you also pay for the amount.

and finally, if you extreme, and go on long hikes in winter sports, then you are most likely ready to spend money on a good warm sleeping bag with a comfort temperature below -10 weighing about 2 pounds. Otherwise you have to rely on the weight of 2700 and 3000 Gy, which is hardly compatible with the heavy winter gear.

Now a couple of tips to extend the life of your sleeping bag:

1) use refills to as little as possible to wash a sleeping bag

2) wash in cold water, no higher than 30 degrees
3) do not iron, do not clean with organic solvents.

4) store in the expanded state, not to leave in a highly compressed state at elevated temperature and humidity

5) in compresses stuff, not folding, not folding into a tube, namely to fill (all brand sleeping bags compresses usually supplied)

6) try not to wet

In General, the manufacturers of sleeping bags we can say the following:

Bask – always high prices, a large selection, including and not the best models. Vaude, Deuter, Salewa - old company with traditionally good quality, fairly high prices.

Red Fox - lot of sleeping bags with down, some with Thinsulate sleeping bags that are extremely outdated. Have a good summer sleeping bags.

Verticale is a good way to buy cheap Polarguard, Warm Loft, but not always good execution.

NordWay – produces along with mediocre models, also cheap with Polarguard (3 models), the performance is of questionable quality.

Alexika – in General, good sleeping bags, a large selection, but consistently underestimated the temperature of comfort (that is actually is designed for warmer weather than written).

Loap - moderate summer and demi-season sleeping bags.

Tramp Best Camp – pretty mediocre sleeping bags.

Campus is very decent for various purposes, good fillers.

High Peak, Husky – moderate sleeping bags.

the review is deliberately not included sleeping bags, designed for extreme mountaineering, polar expeditions and the like extreme. I could see the sleeping bags intended for outdoor recreation and sports tourism.

How to wash a sleeping bag

Drying
- "the Key point drying is transferring the wet bag from the washing machine to the dryer," says Bob Upton, President of the office to repair equipment in Seattle. "When the bag is wet and heavy internal partitions and the stitches may easily break. Carefully place the bag into the bowl, carefully trying to support the whole bag, do not pull on the part of the bag. Show the same care when putting the bag in the dryer. Give preference to the volume of the dryer, preferably one where you can fit yourself"
- To throw down the bags inside 6-12 tennis balls to help fluff to finish.
- Set the lowest and cold mode. For complete drying a sleeping bag will need 2 to 5 hours.
- Periodically check the bag to make sure that the fabric is not too (scalding) hot, and the heater is not stuck and has not developed a lump in one place. If he gathered into a ball, remove the bag and dry it, spread out on the surface.

Additional considerations

- For those who got a sleeping bag from great-uncle: perhaps it cannot be erased. To verify the integrity of such bag, put your hand inside and grab hold of the lining. With the other hand grasp the material from the front side of the bag and gently pull in different directions. If you hear crackling or the sound of thread breaking means of internal walls (or joints) is damaged and need to be repaired before washing.
- the Bag or waterproof membrane external fabric (with a waterproof or water-resistant/breathable shell) will gain a lot of water, so be especially careful when carrying z the washing machine to the dryer. And prepare for the fact that for complete drying will take 4-5 hours.
- Detergents reduce the waterproof properties of materials. Treat your bag after each wash for moisture impregnation, which is in the form of sprays you can find in stores.
