The Zeta 2L HT Insulated Jacket is crafted from waterproof, breathable Helly Tech® PERFORMANCE 2 Ply laminate with an attractive, tweed-like surface design. A quick-dry mesh liner and full size pit zips enhance its breathability. The PrimaLoft® 150g Warmcore insulation will keep you warm in severe weather and a storm flap protects the YKK Aquaguard® front zipper. The full-time hood can be adjusted with one hand. The back yoke has an eye-catching W design, framing a diagonal-stripe reflective element. This is a harness- and pack-compatible design.
