The Devold Expedition Long Johns is a women's base layer designed with double layers for extreme weather conditions. Tested during several polar expeditions, the inner layer is made of 100% merino wool, while the outer layer is composed of 90% Aquaduct-treated merino wool, combined with 10% polyamide to enhance durability.
The Devold Expedition Long Johns offers excellent insulation and has a unique ability to transport moisture. The Aquaduct merino wool is specially designed to move moisture from the inner surface of the fabric to the outer surface where it evaporates.
