The men's Zeta AR is the most versatile jacket for hiking and trekking in the Arc'teryx Traverse Collection. It's protected with a rugged N70p 3-layer GORE-TEX® face fabric. A GORE® C-KNIT™ backer makes it extremely durable, weatherproof, and breathable. This backing fabric is also exceptionally supple, quiet, and comfortable against your skin. The Zeta AR features a trim-fit that leaves rooms for light layers. Its articulated sleeves and gusseted underarms make this jacket extremely maneuverable. The Zeta AR jacket comes with a low-profile StormHood™ that has a ballcap adjuster and provides ample protection. WaterTight™ pit zippers allow for rapid ventilation. The waist has an adjustable drawcord for a more contoured fit. The drop back hem is also drawcord adjustable for enhanced weather protection.
