Devold Expeditiondouble-layer, merino wool base layer designed for extreme warmth. When the Expedition series was tested by Retki magazine in an extensive base layer comparison, it took first place. A full five campfires out of fivethe test team found nothing to improve about the Devold Expedition. Merino wool garments made for cold conditions are exceptionally warm and functional even when damp. Unless completely soaked, the base layer can often be dried simply by wearing it after arriving at camp. Merino wool requires less washing than synthetic fabrics and naturally resists odor build-up. - Double-layer material (Devold Aquaduct) enhances moisture transfer toward the outer layer - The two layers are sewn together, so the structure isnt noticeable when worn - Inner layer: 100% merino wool, fiber diameter 18.7 microns - Outer layer: 90% merino wool (20.5 microns) and 10% polyamide - Flat seams for comfort - Thick 235 g/m² fabric provides excellent insulation - Made in Europe
