Choose the Right Sleeping Bag

Down Or Synthetic?

That a less down-filled sleeping bag weighs and takes up less space than a synthetic sleeping bag (with the same comfort temperature), is basically correct. The development of the synthetic materials is steadily advanced however in recent years, and slow but sure the artificial materials weigh less and less. So far, down produce but still the most heat with low weight and volume.

Down is also almost always the more expensive option, but for a down sleeping bag keeps longer if it is well maintained. When a synthetic sleeping bag the warmth subsides namely after a few years of use, because the filling is gradually compressed and worn out. Should you intend to use your sleeping bag, often in moist conditions, then a model with synthetic filling is preferable. This warms that even if it should become a little wet, which is not the case with a down-filled (if you do not dry the sleeping bag between uses).

In short: you want to minimize weight and volume and achieve the best possible thermal effect, a down sleeping bag is the right choice. If this is not so important you, and your wallet, however, is perhaps a bit thinner, take synthetic fibre.

Length and Fit

Regular, long, 6’6, short, X-long, 185 cm, 179 cm – a sleeping bag model is manufactured in various lengths. There are many length variants, but they have one thing in common: it is always the length of the deck, so the length of the body is the sleeping bag for the. The specified length is 183 cm, people can sleep comfortably up to a height of 1.83 m in this sleeping bag. The inside of the sleeping bag is, however, always slightly longer.

It is a good idea to save the length under any circumstances, nor does it make sense to be too generous. If you choose a short sleeping bag, press your body against the outer walls and tightens it, which leads to the formation of cold bridges. The air that you heat up your body temperature, can no longer circulate and it begins to freeze. If you choose a long sleeping bag, you must warm up more air and keep warm, which leads to the same scenario. In addition, you carry around unnecessary weight and volume with it. No, the sleeping bag has to be just right. You are in the border area for the recommended length of the body, it gets complicated: our advice is then to take the longer version, if you do not want to skimp on weight, volume and space.

It is absolutely necessary to think about whether you are an internal user or a fellow Turner. Want to say: If you can want to turn around inside of the sleeping bag or with the entire sleeping bag. You are the former, then you should consider a sleeping bag in the form of the Mummy into consideration, which is slightly more spacious or but opt for a rectangular model. That would mean a few grams more, but it should be worth a good night’s sleep.

At Outnorth, there are also a number of sleeping bags designed specifically for women. These are slightly shorter in length, somewhat narrow in the shoulder area, better insulated with a proportionately wider cut in height of the waist and the feet. Are a mature rather short and slightly thinner man, it might be a good idea to keep an eye on these models.

Zipper

Most military sleeping bags manufactured by PIMASLEEPINGBAGS are equipped with zippers on the right and left side. For most, it doesn’t matter, but it is always best to have the zipper on the side of your dominant hand. In short: you are right handed, then choose a sleeping bag with the zipper on the left side.

Half-length zip or full length? Again, this is a matter of convenience versus weight and volume. You are a real Hunter of grams, then choose a sleeping bag with zipper in half length. You lose the ability to ventilate the sleeping bag at the foot end, but save a potentially vital weight. Most sleeping bags are equipped with a 2-way zip full length, so that the choice for us mortals is not so difficult.

Nowadays, almost all manufacturers equip their sleeping bags with YKK zippers. This is great, because it allows you to combine two sleeping bags, to have it more comfortable or warmer. However, there is a catch: the zips are produced in various sizes, and for linking together the dimension must match. A rule (for which we have found so far still no exception) is that the sleeping bags in a series have the same zip dimension – for example the series extreme Lite by Western mountaineering, HAGLÖFS censor or Marmot wave. Want to connect two sleeping bags, so it is advisable to select two models from the same series.

With or without membrane?

Some sleeping bags on the market equipped with a membrane, which makes them absolutely waterproof. This has its advantages and disadvantages: you often sleep in the bivouac, under a tarp or similar, a membrane is beneficial. This, the isolation of the sleeping bag is protected from moisture or humidity in any case from the outside.

The catch is that the moisture and steam, your body be output during the night, can not so easily escape as a membrane tissue is denser than a nylon fabric without membrane. This can be solved by keeping the temperature inside of the sleeping bag, so that the ventilation is sufficient. Another option is to use – VBL also referred to as a “sweat catcher” which stands for “Vapor Barrier Liner”. Therefore, this sheet acts as a vapor barrier, which keeps the moisture of the body during the night. A sweaty affair, but this one has a dry sleeping bag in the morning.

You are first and foremost a three seasons user, who sleeps in the tent, a membrane of less is important because it makes heavy and voluminous the sleeping bag. Better invest in a good tent, which keeps the moisture out. Should you be worried that the foot end of the sleeping bag will wet through contact with the tent wall: take your Hardshell jacket on, and the problem is solved.
