Wear the wicking Helly Hansen men's HH Warm Pants as a base layer when the mercury plummets. This HH Warm pants feature insulating, soft, non-itchy merino wool along with hollow synthetic fibers that trap heat the same way polar bear fur does. The result is that you stay warm and dry when you ski, snowboard, mountaineer, or hike in cold weather. HH Warm is the natural choice in sub zero environments, this baselayer features two different layers in one. The inner mesh features the unique, hollow Lifa® T3 (Thermic Tube Technology) that mimics the fur of polar bears. This means you get extreme insulation and superior evacuation of moisture. The outside of super fine merino wool adds warmth - with zero itch-factor.
