Cold days demand baselayers that perform. The Atomic Baselayer Long Tights M combine warmth, breathability, and unrestricted movement through a seamless merino-wool blend knit. Body-mapped zones bring warmth where you lose heat and ventilation where you build it, maintaining comfort and wicking moisture as efforts rise and fall. Soft next to skin with four-way stretch, these full-length men’s baselayer tights maintain a streamlined fit without bunching. With moisture managed and temperature steady, comfort stays consistent. Performance-driven thermal baselayer pants for storm days, long tours, and every ski day in between.
