With our new EBTek series, we bring back our signature performance activewear from the 1990s, updated with today's technology. Like the originals, these pieces are made with superior-quality materials, constructed to withstand the most active pursuits, and styled for maximum comfort.The robust, 400-weight polyester microfleece in our EBTek full-zip mock is exceptionally warm without feeling heavy. Nylon overlays on the shoulders, back yoke, and neck exterior are treated with a water-repellent finish that beads moisture so it rolls off the surface. The full-zip front has a storm flap with hook-and-loop closure. Gender-neutral sizing.Models Shown: Female 5'9"-5'11", Size S; Male 6'0"-6'2", Size M
