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. And stretchy jersey panels with gussets and articulated elbows 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.
