When a hardshell is too much and a midlayer is not enough, the Kor Preshell™ Hoody is the layer youve been missing. Its both weightless and water-resistant?durable and pliable?roomy and stows in its own pocket. Call it an ultralight softshell or a super breathable wind shirt, but we just call it the do-it-all stretch layer for cool-weather trail runs, aerobic ski tours, big alpine rock routes, and...well, just about everything.
