An intimate blend of spun and filament yarns, Terramar Thermolator Thermal Underwear transports moisture without sacrificing warmth and softness. The EC2 Quick-Dri bi-component knit construction optimizes the movement of moisture away from the skin and dries quickly, and the thermal knit outer creates warmth-trapping air pockets. The universal garment design makes Thermolator the ideal base layer for a broad range of cold weather activities.
