A minimalist shell built for demanding day hikes and backpacking trips in harsh conditions, the Arc'teryx Women's Zeta LT Jacket reduces unnecessary bulk with its streamlined, no-nonsense design. Weighing only 10.6 ounces (size medium), the Zeta LT Jacket won't take up all your pack space or slow you down during fast-paced missions in the backcountry. Its Trim fit sits close to your body while facilitating essential layers underneath. Articulated patterning promotes unrestricted motion along the elbows and underarms where it's needed most. Gore-Tex 3-layer construction offers impeccable waterproofing, meaning you'll stay pleasantly dry in heavy rainstorms and soaking environments. This particular Gore-Tex construction features a C-Knit backer that lends a supple feel, with enhanced breathability to eliminate clamminess inside the shell. WaterTight zippers along the front closure and hand pockets prevent moisture from seeping through the jacket's vulnerable openings. Creating a soft-wearing feel, the brushed microsuede collar won't irritate sensitive skin when you're hunkering down in rainy weather. The low-profile StormHood features a one-handed adjustment for quickly sealing out the elements, as well as a laminated brim that re-directs moisture from pouring inside.
