Discover warmth and comfort in the great outdoors with our Men's Thermolator Performance Pant. These versatile thermal long johns are designed with an ultra-soft, mid-weight fabric and feature ClimaSense Thermoregulation Technology. This technology adjusts to your body temperature by trapping air to maintain warmth when you cool down and allowing moisture vapor to escape when your aerobic activity increases. Whether you're skiing, mountaineering, biking, snowshoeing, or just enjoying winter outdoors, Thermolator delivers functional performance at its best. The pant's ultra-soft brushed fabric surface traps air for warmth, and its UPF rating of 25 offers sun protection. Flatlock seams, 4-way stretch, and gusseted panels ensure ease of movement, while odor-locking technology keeps you fresh. With a 28.25" inseam and ankle-length fit, these pants are your ideal choice for versatile warmth. Crafted from 86% Waterless Dye Polyester and 14% Spandex, they're durable and flexible. Machine wash in cold water with dark colors separately, tumble dry low, and skip fabric softener and dryer sheets for the best results.
