The Devold Expedition long johns offer exceptional insulation and have been used on several polar expeditions.
 
Devold Expedition Merino long johns are a two-layer wool base layer designed for extreme weather conditions, tested on multiple polar expeditions. The inside is made of 100% soft merino wool, while the outside consists of 90% Aquaduct-treated merino wool. The Aquaduct treatment in the outer layer enhances moisture absorption from the body, quickly wicking it away to evaporate, keeping you dry. We also use 10% polyamide in the outer layer to increase durability, ensuring the garment can withstand the toughest expeditions. Expedition wool base layers offer exceptional insulation and unique moisture-wicking properties, making them the solution for the coldest days – whether you're a polar explorer or not.
