Skin track, singletrack, alpine crack—for fast-paced pursuits where a hardshell is overkill and a midlayer fleece lacks protection, the Kor AirShell™ Hoody is the ultralight, ultra-packable layer of your dreams. This durable yet super-breathable jacket rebuffs light moisture and cuts through alpine gusts thanks to its Pertex® Quantum Air fabric, and stows in its internal pocket when conditions ease up. Call it an ultralight softshell or a super breathable wind shirt, but we just call it the do-it-all layer that never leaves our pack until the moment strikes.
