Our Opinion The weight and the compressed volume?
The weight of your sleeping bag is an important consideration if you are hiking or trekking.
The best weight / temperature is present in the sleeping bags down. You will not find very light sleeping bag with low comfort temperatures.
In order not to overload you with too large bag, the compression volume is also an important criterion. The down sleeping bags compress better and are usually less bulky than synthetic sleeping bags.
Our Opinion What filling: down or synthetic?
-loses its insulating ability when wet
-less resistant to moisture
-It is more resistant to moisture
-A percentage is specified to give the percentage of down and feathers used (eg 80/20 means that the lining is made of 80% down and 20% feathers). The use of feather is indeed essential to ensure the best power down the swelling.
-The extent of the swelling power in Cuin (cubic inches) gives the quality of the down and its insulating capacity. The value indicates the volume of an American ounce of down (28.35 g). More fluff has been carefully sorted, plus its swelling capacity is important.
A down sleeping bag will be suitable:
-for long walks because the lightness and compactness are important criteria;
-For comfort and if you sleep in the shelter (tent, shelter) or in the open in dry weather.
A synthetic sleeping bag is suitable:
– if it can be exposed to moisture (high humidity, nights under the stars);
– If you are looking for an economical solution for a short hike or from hut to hut because, in this case, your backpack is not too heavy, and the weight of the sleeping bag will not be a determining factor. According to professional backpackers, this type of sleeping bag is great for backpacking.
Our Opinion Some criteria to consider
Remember to take into consideration:
-the geographical area of your excursions;
-Altitudes where you sleep;
-The bivouac conditions (stars, tent, shelter …)
-the season ;
-Weather conditions (temperature, but also the risks of bad weather). Warning: even in temperate zones in summer, the temperature can drop significantly at night since you are at altitude.
– Moisture and wind
The cold sensitivity is different according to the constitution, the degree of training and gender of people: if you are chilly, remember to take a bag with a slightly lower comfort temperature as temperatures which you think you are experiencing. You’ll have more cold if you’re tired and you have not eaten.
Our Opinion Comfort temperature: at What do the indicated temperatures?
We show you three temperatures: comfort, comfort limit and risk of hypothermia.
You must first look at the comfort temperature that will serve as reference in your choices, not the temperature limit of comfort, much less the temperature risk of hypothermia.
Here at What do the three temperatures:
-Comfort temperature: this temperature until the subject in a relaxed position on the back, is generally “comfortable”, that is to say, it is in thermal equilibrium and feels no cold (determined for a woman weighing 60 kg).
-Temperature limit of comfort: this is the limit temperature at which the subject, curled up on itself in the sleeping bag, is at the limit of feeling cold (determined for a man weighing 70 kg and under normal conditions of use). This position is adopted to minimize the body surface loses heat.
-Temperature risk of hypothermia: the temperature appears where the risk of hypothermia can lead to death (determined for a woman weighing 60 kg, curled up under normal conditions).
