Insulation for aerobic pursuits.

Slightly heavier than the RaceX Speed Top, Swix's RaceX Warm Men's Midlayer Top uses the same fabrics and a similar design to help you stay warm during chilly winter runs and recovery-speed ski days. It's made primarily of Polarec Thermal Pro fleece, which wicks moisture, insulates efficiently, and features stretchy side panels that won't interfere with high-speed V2, casual V1, or your morning jog. The Lycra cuffs have thumbholes to help seal out drafts, and the slim side pocket is a great place to stash your phone or house key when you're on the go.
