Description The laws of thermodynamics dictate that heat will always move to colder areas. Well, not anymore, because with the Thermic LL base layer, we’re fighting physics with physics. Engineered with hypoallergenic Dryarn® fabric in very specific, strategically placed knitting patterns, our R&D managed to create a base layer pants that actively insulate body heat. Meanwhile perspiration is wicked away, absorbed by the fabric, and allowed to evaporate away from the skin, preventing the moisture from conducting between the cold outside and the heat inside. Even the elasticated waistband and bottom hems are designed so the base layer comfortably wraps around waist and ankles, preventing heat from escaping. Much more than just underwear By effectively trapping body heat, your body is less strained to keep your body temperature up by burning calories and consuming energy. Energy you could be putting to good use in staying sharp and staying focused, proving the Thermic LL base layer pants are much more than just simple underwear.
