Wear it once and you won't want to take it off again. The simple insulating jacket was born out of the necessity to offer outdoor athletes a lightweight and as simple as possible piece of functional thermal insulation clothing. It can be used as a top jacket when trekking or moving on snowshoes, or as an insulating layer when skiing downhill or climbing uphill. Thanks to the premium Primaloft® material, this jacket offers great thermal insulation properties and superior breathability in sub-zero temperatures. Despite the humidity, the Primaloft® material loses almost none of its insulating properties, as happens with down. The jacket dries quickly and can be conveniently packed into a small volume. The top material is elastic and very pliable. The extremely breathable and elastic Polartec® Power Wool® material in the armpit ensures that excess heat is dissipated as quickly as possible.
