Description

Aerial 250 false bottom sleeping bag features specialized construction, perfect for discerning adventurers who demand the peak of lightweight performance without compromising on comfort. Its exceptional ratio of weight to insulation level is not only achieved through the use of ultralight fabrics and 900 FP down fill but also through innovative design solutions.

While sleeping outdoors, the main insulation from below is primarily provided by the sleeping pad, as the insulation in the bottom part of the down sleeping bag compresses under the sleeper's body weight. Therefore, to reduce weight, the Aerial series features only a single layer of ultralight Toray Airtastic® fabric on the bottom part, eliminating the need for additional down fill. Additionally, the precisely crafted design of “H” chambers and the absence of a zipper firmly position the Aerial 250 sleeping bag among the top ultralight products. With a mere weight of 13.5 oz grams and a comfortable temperature level of 35 °F, it sets a new standard in the world of down sleeping bags. Its exceptional thermal performance at such a weight is unmatched by its peers.

Extreme adventure pursuits, long-distance cycling races, or multi-day hikes in technical terrain are scenarios in which the minimalist Aerial series of sleeping bags will prove most effective. It is also the go-to choice for those who carefully consider every gram of equipment carried on their own back, so they can embrace the freedom of lightweight adventures.

Down

 

Years of breeding experience, a specific climate and research facilities are the secrets behind the excellent parameters of Polish down, which is considered to be the best in the world. Despite technological advancement and attempts to make artificial insulation that would be just as reliable, down still remains unrivaled.

It is from free-range geese that have access to water. The excellent breeding conditions are also reflected in the down’s high quality.
