Made with an - friendly, Pfas - free waterproof membrane, partially materials, and go - anywhere features, our Backcountry Cardiac Gore - Tex 3L Jacket is a full hardshell quiver in one - friendly package. The 3 - layer, seam - sealed construction is weatherproof yet breathable, while the body - mapped stretch panels increase airflow and elasticity right where we need it. Whether it's a bluebird day at the resort or we're climbing steep skin tracks, the underarm zips, vented storm flap extension, and two - way front zip let us choose how we turn up the air. And wherever we harvest powder, the low - profile snow skirt, tall tricot - lined collar, cinchable hood, and adjustable cuffs armor us against powder spray.
