Travel sleeping bag is a sophisticated sewing product, in the manufacture of which used fabric and insulation, as well as various accessories (zippers, ropes, buckles).
From these materials depends on how light, warm, waterproof will be a tourist, the prices of which still largely shape the brand and temperature range for which they are intended. Types, models, heat resistance sleeping bags can be read here.
English names and numbers from the labels, of which not all though saying something to the buyer, in the best case, will help to identify natural or synthetic fabrics and insulation it is sewn.
For making travel sleeping bags use materials of different kinds. And in this article we take a closer look at the most common.
Sleeping bags travel: the front and lining fabric
Nylon (Nylon). The most common fabric for sewing a sleeping tourist. There are different densities and with different properties (waterproof, windproof or membrane). Used as outer and as lining.
The type of nylon fabric, in the weaving of threads which you can see the cage — thicker vodana the filament, raising its resistance. This is usually referred to as Rip Stop.
Polyester (Polyester). Also quite popular. Stronger and heavier than nylon. Also used as outer lining and as the fabric.
Cotton (Cotton), cotton flannel, natural fabrics. In some models it is used for interior lining parts. Pleasant to the body (in comparison with slippery nylon and polyester).
The lining of the tourist sleeping bag can be sewn from linen, wool and combinations thereof. Natural fabrics are pleasant to the touch structure, allowing you to sleep without underwear, but they are heavier and stronger artificial absorb moisture.
Polycotton (Policotton). Blended fabric consists of polyester and cotton at different proportions, "middle," between an artificial and a natural lining. To the touch it is similar to cotton, but lighter and faster drying.
Insulation synthetic and natural
The insulation materials used in sleeping bags can be divided into 3 groups.
Types of insulation sleeping bags travel
- synthetic (different composition)
- natural (fluff)
- combined(the top, playing the role of Comforter with a down insulation
bottom – "the coating", synthetic)
Synthetic insulation, at present, already not are a cheaper alternative to feathers, and compete with him, playing, while, from the point of view of warmth and ease, but winning due to the low hygroscopicity (blagovijesti).
Because the warming effect is provided by air spaces between the fibers of the insulation, and when it becomes wet, then they disappear, and with them the insulation.

- Double sleeping bag: types and models
- Baggy exotic: functional retro and hipster style
Since there are no specifications on the technical characteristics and composition, any synthetic insulation can be called synthetic padding. But to avoid confusion we will call artificial insulation according to accepted trade names. Definitely recommend them to find in the product description that you need to carefully examine before travel to buy.
Polyester Batting (Sintepon). Used in the most inexpensive camping models, usually slender, K. the batting heavy. The composition is tangled or glued synthetic hairs from polyester, most often in Belarus.
Left to right: polyester, hollofayber, fiberteck
Hollofayber (Hollowfiber). In General, the same polyester, but in a more modern version with hollow hairs – "pasta" made from the same polyester. In comparison with synthetic padding softer, insulating properties above. Is the most common insulation for sleeping bags and travel clothing.
Produced in Moscow factory termopol. Many Chinese products in the composition of their products is called insulation holofayber, but who knows what actually.
Fiberteck or Fibertex (Fiberteck) these are the same "spaghetti" from polyester, mainly the production of Belarus or Ivanovo, but is coated with silicone, which increases their elasticity and moisture barrier properties.
Primaloft (PrimaLoft) — the U.S. polyester fiber, the manufacturer claims that its main advantage is the insulating properties, due to which it retains moisture and wind, while it removes from the body sweat.
Thinsulate (Thinsulate). One of the oldest synthetic insulators, invented back in 1978 by 3M company (USA). Is a matted fiber on the principle of the same pasta, but of a different material, containing approximately 75% Dacron and 25% polypropylene. This allows it, unlike the above-mentioned insulation to be less hygroscopic. Sleeping bags for travel with this special Thinsulate with improved compressive properties.
Manufactured in different enterprises, but only 3M ensures quality and safety (harmlessness). Manufacturers using this material in their products, declare him the present. I don't know, can you call the technology, which is 38 years a modern?!
Holofil (Hollofil). This material, indeed, fresher. The same "macaroni" technique, but the material is Dacron. This insulation is used in high-end models with the claimed high thermal stability and ease of the product.
Different manufacturers name this material different. For example, isotherms (Izoterm), technofiber (Tecnifibre) — fibers have not one, but several channels, polarguard (Polarguard) channels is not circular, but triangular, which makes the structure more resilient insulation. But all this is essentially one of holofil.
It is clear that modern foreign lightweight insulation "Inbox" in tourism, the prices still on them are higher than sleeping bags, for example, with synthetic padding.
NATURAL INSULATION FLUFF (DOWN) SLEEPING BAGS
As a natural insulation sleeping bags winter tourist uses fluff a goose or the other, necessarily, waterfowl. Different quality (the ratio of down and feather), the higher the quality of down, the higher markings.
The highest quality products from down with marking 550-800 indicator is referred to as "fill power" — the ability of down to regain its volume after compression, E. elasticity.
As stated by the manufacturers and sellers of artificial insulation on their superiority, but protection from the cold none of them exceeded. Fluff average quality is much warmer than most of new synthetic insulators. Keep this in mind before you choose a travel sleeping bag.
Left to right: synthetic insulation, down
The main disadvantage of down sleeping bags – hygroscopicity. Despite the natural fat impregnation downy hairs, still absorbs moisture, it is difficult to dry in field conditions.
A more detailed analysis of the advantages and disadvantages of down and synthetic winter sleeping Meshkova doing in a separate article.
A few words about the combined sleeping bags. This is a fairly rational option. Downy top serves as a blanket, and "litter" with synthetic insulation", compressed by the weight of a person, it is still not the main insulator. In this case the role of the Mat (sleeping pad). Besides, there is always the risk that the sleeping bag may podteret bottom, which is not critical for quick-drying synthetics.
