The Expedition Merino 235 Long Johns are part of the Expedition series by DEVOLD and are an underwear garment designed with dual layers for extreme weather conditions that is proven on several polar expeditions.

The inner layer is made of 100% wool (Merino), while the outer layer is 90% Aquaduct treated Merino wool, combined with 10% polyamide to improve durability. The Expedition Merino 235 Long Johns by Devold for women insulate extremely well and have an unique ability to transport moisture.

The Aquaduct Merino wool is specifically designed to move moisture away from the skin side of the fabric to the outer surface where it evaporates.
