Men's Headwind JacketLighter than air and super packable, the Headwind Jacket packs a major punch for something that folds down to the size of a tennis ball. The wind resistant shell keeps gusts and chills out, while still letting your skin breathe. And unlike most windbreakers, it isn't crinkly or stuffy instead it feels like a barely there second skin. Topped off with a DWR finish, this jacket easily fits in your daypack, carry on, or fanny pack (yes, it's that packabe)
