The Ice Crew combines LIFA® fiber technology with merino wool to deliver exceptional warmth and moisture moving management at a minimal weight. Flat lock stitching and low bulk cuffs reduce chaffing during dynamic activities in cold environments. HH®Warm™ is the natural choice to stay warm in sub zero environments. This baselayer features two different layers in one. The inner Lifa® fibers ensure you stay dry in all conditions, while the outer, soft Merino wool adds warmth and comfort. This means you get extreme insulation and superior evacuation of moisture.:
