A down sleeping bag is usually filled with goose or duck down and feathers. It is the warmest type of sleeping bag available on the market. Natural down is characterized by its lightness, softness, durability and compressibility. For winter sleeping bags, the ratio of feathers to down is usually 90/10 or 80/20, while in models designed for autumn and summer the ratio is about 70/30 or 60/40. It is worth noting that the higher the proportion of feathers, the warmer the sleeping bag.
When is it worth choosing a down sleeping bag?
A down sleeping bag is worth choosing if, for example, you plan to sleep at high altitudes (above 3,500 meters above sea level), where temperatures can be extremely low, as it provides the best insulation and thermal comfort. In addition, if you need to save space and weight in your backpack, an ultralight down sleeping bag that can be heavily compressed will be a better choice than a synthetic counterpart.
However, it is worth remembering that down is sensitive to moisture and can lose its insulating properties when soaked with water. Therefore, in situations such as thaw, wet snowfall or damp weather, a synthetic-filled sleeping bag is a better option.
What is an ultralight down sleeping bag?
An ultralight down sleeping bag is a lighter version of a down sleeping bag, designed to minimize weight and volume. It is worth noting that some down sleeping bags can be quite heavy, which depends on the materials and construction used. However, there are special lightweight down sleeping bags on the market, which are a great choice for people who want to reduce the weight of their backpack, for example, during long-distance hikes. Such sleeping bags often weigh less than one kilogram.
Down sleeping bag offer at MILITARY.EU
We offer down sleeping bags from brands such as: Fjord Nansen, Volven and Carinthia. You can choose from envelope-shaped down sleeping bags, as well as those with an H-shaped chamber design, which eliminates the effect of down shifting and clumping.
The sleeping bags are made of durable materials, such as 10D nylon with a Rip-Stop weave, which makes them highly resistant to abrasion. Selected models are additionally coated with a hydrophobic layer to protect against moisture. Depending on the model, sleeping bags differ in additional features. For example, some are equipped with a zipper with an Anti-Bite system, a drawstring at the top, loops for mounting a liner, a bottom drawstring, and Duo rubber bands that allow adjustment without leaving the sleeping bag.
