The FTC Thermal is Endeavor's perfect thermal layering system. The bottom is a tailored fit made of cotton-like moisture wicking fabric Endeavor call Drytech. A brushed soft back is luxurious against your skin while the tight knit construction ensures sweat is quickly wicked so you stay warm and dry.
Match it with the FTC Thermal top and you've got yourself a perfect thermal pair there, partner!
