Built for the unexpected, the Impermeo 3L Hooded Jacket is a waterproof and windproof shell for coastal hikes and summer thunderstorms alike.  Fully seam-sealed, three-layer protection fights off the elements, while two-way stretch keeps you cruising along the trail. Built-in adjustability lets you dial the fit for maximum protection, and the whole thing packs into a pocket for easy storage when the sun pokes through.
