Designed for versatility with a focus on trekking and hiking, the Women's Zeta AR Jacket is made from three-layer Gore-Tex fabric with C-Knit backer technology. This material delivers durable waterproof, windproof, highly breathable protection with a backer technology that makes the fabric exceptionally supple, quiet and comfortable. Arc'teryx' Trim fit keeps the shell close to the body to improve the Gore-Tex fabric's breathability, but leaves room for light layers. Articulation in the sleeves and gusseted underarms provide freedom of movement.Hardwired for the trail, the Zeta AR is built for exploring big terrain. On extended outings or when working hard in mixed conditions, the water-resistant pit zips provide rapid ventilation. The low profile Arc'teryx StormHood delivers full protection and cinches securely with a single adjuster for a fit that moves with the head and provides exceptional peripheral vision. The hip length with drop back hem extends coverage and rides comfortable under a hipbelt. An internal laminated pocket stows and protects a smartphone or wallet, and two hand pockets with water-resistant zips are accessible while wearing a pack or harness.
