The Expedition Arctic Pro Longs 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.

In the harshest, most unforgiving environments on our planet, DEVOLD Expedition Arctic Pro stands as your unmatched choice. Developed in collaboration with polar explorer Borge Ousland, the Expedition Arctic Pro Longs are the warmest and most insulating baselayer to date.

Extensively tested in extreme conditions, the Expedition Arctic Pro Longs are the culmination of cutting-edge design and durability. Comprising three distinct qualities from the existing DEVOLD collections, they are a blend of the moisture-wicking Aquaduct-treated Expedition (90% Merino and 10% silk), insulating Egga Grid, and the ventilating Wool Mesh. Together, these materials make this baselayer your armour for survival.
