Mountain Hardwear Warp Factor Anorak - Men's Shark, L

The Warp Factor Anorak trades a full-length zipper for a half-zip pullover build, keeping the DrySpell 2-layer nylon ripstop shell close to the body without added hardware up front. The ripstop itself skips the stiff, plasticky hand we expect from a waterproof shell, draping more like a densely woven textile that moves with the body. A water-resistant Vislon zipper with a chin guard and draft flap seals out wind at the collar, doing double duty since the half-zip build has no full-length seam to guard elsewhere. What Our Gearhead(R) Experts Are Saying:"I skin up in this, and the mesh-backed vents dump heat fast enough that I never have to stop and strip a layer at the ridge. That's the kind of margin that matters more than a chest zipper ever would when I'm running hot on the way up."
