Arc'teryx Beta FL Jacket

If you're the kind of guy who moves fast from dawn til dark in the mountains and doesn't tolerate an ounce of extra weight, this is your jacket. Super light at 11.4 ounces and conceived with breathability uppermost in mind, the Arc'teryx Beta FL Jacket uses the latest GORE-TEX® Active Shell membrane to keep water from getting in while letting sweat escape. Built with minimalist GORE-TEX® N30p-X fabric in the body and higher denier N40p-X in high wear areas around the sleeves and waist where your harness and rope touch, this jacket is tremendously tough as well as feather-light. Streamlined e3D fit means skip the donut and go for a run instead.
