This vest is amazingly durable and dependably water repellent, rolling with the punches when the rain rolls in. It is lightweight yet warm and can be worn by itself on cooler days. The vest features a 1.75-ounce, 100% nylon Cordura shell with Rain Defender durable water-repellent Nylon lining quilted to 100g polyester insulation. It also includes a mock-neck collar, a left-chest map pocket, and two lower-front pockets.
