It is important to understand that in a sleeping bag is not any heating element, i.e. it does not heat. Its function is to achieve an optimum temperature to sleep in a nice position, thus preventing the heat generated by the body itself escaping abroad. It is basically an insulating element which should ensure maximum possible isolation, even in the most extreme environmental conditions. For this reason, according to the place in which it is to use the sleeping bag, the requirements will be more demanding. It is not the same to sleep in a tent in the high mountains that sleep in a shelter, make bivouac or use the sleeping bag at a campsite at the level of the sea. (more…)
The sleeping bag is the element that will allow us to spend a night in the mountain, either in a shelter or bivouac, causing our body temperature to stay within the proper limits to achieve a pleasant and restful sleep to continue our Activity the next day with sufficient strength.Next we will detail in technical way each one of the parts that compose a sleeping bag. (more…)
Liners (or meat bags) are ideal for protecting the interior of the sleeping bag soil, avoiding washing too often and thus increasing the lifetime. These inner bags are either cotton or silk, and sometimes fleece.
Silk liners are very light (approximately 130g) and provides a heat gain of 1 to 2 ° C maximum. Cotton meanwhile is heavy (300-350g) and not heat, but it has the advantage of being cheap.
Like many outdoor items, sleeping bags are 99% have a down or synthetic insulation. Each with its advantages and disadvantages, simply target the use you make of your sleeping bag to determine the type of insulation that best suits your needs.
There are obviously different insulating qualities of down. You may have noticed the numbers that follow the words down: 550, 600, 650 … 800. This corresponds to the down swelling capacity; the higher the number, the higher it is quality.
By cons, the figure does not correspond to the heat that provide insulation, rather it depends on the amount of fluff inserted into the sleeping bag.
Thus, for 1 gram insulation, down 800 will be hotter than 550 fill down.
Please note that it is quite normal to see fibers escape from the sleeping bag; this is not a sign of a manufacturing defect nor a sign of inferior quality, the warmth of your sleeping bag will not be affected. The most important is not to pull on the fiber, but rather to try to place it inside. It’s the same technique that should be used if your down coat loses its feathers .
Based on topbbacolleges, the advantages of down sleeping bags are mainly lightness and compressibility. It is therefore ideal for expeditions. Despite the water-resistant coatings applied to the insulation, moisture can still affect the thermal capacity of down, so it is especially appreciated for fresh and dry environments.
In brief: lightweight, compressible, warm, durable, less effective in high humidity and very comfortable.
Synthetic insulations are usually sleeping bags heavier and less compressible. However, they are ideal for high humidity since they retain their heat capacity. The possible arrival on milkweed market promises much in the field of synthetic insulation. It is ideal for very wet areas or for casual campers have access to a car since the compressibility and weight are then less of a factor.
In brief: inexpensive, heavier, less compressible, retains its thermal capacity when wet, not allergen.

You plan to practice for a few days a sport outdoors, such as hiking and camping? Do not forget your sleeping bag, essential equipment for sleeping and protect against rain and cold.
The principle of the sleeping bag is to allow your body to keep warm. To help you find the right sleeping bag, Solentbay proposes to carry out a comparative test between two sleeping bags that are distinguished by several criteria.
Always in search of the best quality / price for sleeping bags to sleep without trying the winter in our mountains, today I’m interested in a well-known fluff that comes from living a transformation. The North Face wanted a new Blue Kazoo lighter and less conducive to compression on sensitive areas. Let’s see what happens after a first battery of tests without winter bivouac tent or outer bag.
Down is the element that will keep you warm on cold and rainy nights in the green. If you want to avoid spending your night shivering in the fetal position trying to warm up, it is advisable not to choose her down lightly. Out today there are dozens of features on down, shape, volume, composition … Here we will attempt to guide you in choosing your sleeping bag so you can spend nights comfortable.
Keystone Construction: Used in shipping sleeping bags Down, this construction allows positioning the opposite side face to face to eliminate possible ‘cold spots’, to keep a constant volume while keeping the down in place.
Two different outer fabrics: on top, a blue 22-denier ripstop nylon fabric, beneath a gray fabrics 30 denier Nylon Taffeta (see video). The blue part has a “ripstop” mesh (small squares) avoids a possible tear to expand, the gray area has a higher denier, more abrasion resistant;
The lining is gray goose down Hungary , 90/10, 650 cu.
Overall a well-studied down with a good comfort of use especially in connection with the swelling and the quality of interior fabrics.
The ability to open the bottom of the zip allows versatile use by temperatures above 5 ° C to + 10 ° C opening downwards and leaving enough open up.
The relative width of the down allows use by temperatures below -4 ° C with a jacket or more thinner layers.
A sleeping bag or duvet coat is among the most important items to carry in your backpack. Over time, the accumulation of moisture from transpiration, food and dirt stains can however lead to deterioration of the insulation and the fabric.

Since 2002, the European standard EN 13537 allows to seamlessly assess the operating temperature of a sleeping bag. It allows to compare products of different brands. However, it is not mandatory, we must pay attention to temperatures mentioned by some manufacturers, and check the reference to the standard of the sleeping bag.
Synthetic fibers are an alternative to down which have the advantages of being more resistant to moisture but also more economical. They are for people who make very long journeys where a cleaning may be necessary, or have something else to manage the humidity in their sleeping bags.
Since March and I returned to France, I have actively taken up the mountain trips and bivouacs. This time, I decided to relieve myself and upgrade my equipment from lighter and with quality materials. Priority was sleeping bag because I had only summer sleeping bags with lumite comfort to 8 ° c thus clearly unnecessary for overnight stays at 2500m in late winter / early spring and finally even the summer. I wanted a sleeping bag with three criteria: light, warm nights down to-2 ° c at least with an exorbitant price. During my research, I found what I needed but more than 400 or 500 €, largely off-budget. A friend told me about the Cumulus brand, a Polish brand not well known but high-achieving bags. He opted for the Liteline 400 for his trip to Iceland, you can see the pictures here , after comparing with the model just above my choice finally focused on Panyam 450.
Night in Chamonix was much warmer, around 4 or 5 ° c, I slept in a place with little space and can not plant the sardines to stretch the tent, but the stones held an assembly far from ideal, a few centimeters of a stream that feeds a lake. An air current snuck into the night in the tent while I was sleeping with open zip, I just closed the zip and adjusted the non-chill rim and went back to sleep worry-free overnight. Before, under similar conditions, I slept with systematically in thermal wear, now I normally sleep in the silk cloth inside the bag. The cut of the bag is fitted but not too tight, perfect to be able to move a little in and the hood is really nice. She remains under the head even if you move, a real good point.
During our stay in Iceland we were only comfortable sleeping bag, warm and compact. We therefore turned to Pyrenex, a French brand upmarket, who offered us two sleeping bags to test them during our stay in Iceland! We deliver you our impressions and opinions!
