The North Face Summit Series Men's L3 Jacket is an insulated midlayer for climbing pursuits into unpredictable alpine environments. The L3 is all about being ultralight and warm, and the 800 fill goose down allows it to do just that. The FuseForm™ nylon fabric seamlessly transitions from micro-ripstop to mini-ripstop, providing you with durability where you need it most. All the pockets are zippered to stash small items on your person, for quick access mid-climb. Wear it when you need it, stash it in your pack when you don't.
