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 lightweight, soft, durable and compressible. In the case of winter sleeping bags, the feather to down ratio is usually 90/10 or 80/20, while in models intended for autumn and summer, these proportions are around 70/30 or 60/40. It is worth noting that the higher the feather content, the warmer the sleeping bag.
When is it worth choosing a down sleeping bag?
A down sleeping bag is worth choosing, for example, when you plan to sleep at high altitudes (above 3500 m above sea level), where temperatures can be extremely low, because it provides the best insulation and thermal comfort. Additionally, if you need to save space and weight in your backpack, an ultralight down sleeping bag that can be compressed significantly is a better choice than a synthetic equivalent.
However, it is worth remembering that down is sensitive to moisture and can lose its insulating properties when soaked with water. For this reason, in situations such as thaws, wet snowfalls or humid weather conditions, a sleeping bag with synthetic filling 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 bulk. It is worth noting that some down sleeping bags can be quite heavy, depending on the materials and construction used. However, there are special lightweight down sleeping bags on the market that are a great choice for those looking to reduce the weight of their backpack, for example when hiking long distances. Such sleeping bags often weigh less than one kilogram.

Sleeping bags are made of durable materials, such as 10D nylon with a Rip-Stop weave, which provides them with high resistance to abrasion. Selected models are additionally covered with a hydrophobic layer that protects against moisture. Depending on the model, sleeping bags differ in additional functions. For example, some are equipped with a zipper with the AntiBite system, a top drawstring, loops for mounting a liner, a bottom drawstring and Duo rubber bands, which allow adjustment without the need to get out of the sleeping bag.
