Originally developed for the space program, ultra-light Aerogel polyester adapts to your body temperature for out-of-this world regulation. So it was the perfect insulation for the AirLoc base layer system. Engineered with body-mapped quilting for targeted warmth where you need it most. Stretchy jersey panels and a Crouch Gusset® flex when you do. Plus, the soft fabric is finished with flatlock stitching for optimal next-to-skin comfort. No bulk warmth – no reason to stay inside.
