SockGuy EliteTech Base Layers offer a super soft, next-to-skin fit with ultra-wicking performance. We developed our fabrics specifically as a lightweight moisture transfer syste to keep the next-to-skin surface driest and dramatically increase evaporation rates. Combined with our Cool Comfort Construction techniques, the fit of EliteTech Base Layers optimizes moisture transfer without constricting movement or adding bulk. ProLite is our lightest sleeveless base layer with super stretch open-mesh to provide superior ventilation and moisture transfer for high temps and indoor training. 85% Polyester / 15% Spandex super soft, next-to-skin fit ultra-wicking performance Cool Comfort Construction techniques ProLite is our lightest sleeveless base layer 85% Polyester / 15% Spandex
