If you're serious about all-season outdoor adventures, or if you just occasionally find yourself in a downpour, this rain jacket is for you. The ultralight nylon shell is fully waterproof and breathable with seam-sealed construction and features a durable, water-repellent finish that causes moisture to bead and roll off rather than soak into the fabric. Because it's lightweight and folds compactly into the right hand zip pocket, it's easy to tuck into a pack, duffel, or briefcase so you're always prepared.
