Weighing in at a ridiculously light 4.5 ounces, the Eyebright Jacket is handmade in the brand’s Portland, Oregon, headquarters. Not only is each jacket laser cut for a precise fit, but it features a waterproof and breathable shell made from Dyneema, a composite fabric famous for its legendary strength-to-weight ratio: it’s 30 percent lighter than nylon/polyester and 15 times stronger than steel. NW Alpine spent four years to develop the Eyebright, which combines Dyneema with an eVent waterproof membrane, alongside innovative no-sew seam taping construction, in which the only sewing you’ll find on the jacket is in the zippers. This is the only lightweight shell you’ll need when you hit the mountains this summer.
