Eiger Nordwand in winter The Rockies in January Antarctic fantasies The Patagonia Women's Northwall Jacket combines toasty warmth and full-on alpine protection with lowland breathability. Its exclusive package features Polartec(R) Power Shield(R) Pro fabric bonded to our Regulator(R) R2(R) grid interior - the result is an extremely breathable soft shell that's functionally waterproof in all but a deluge. The insulation-shell combo is minimalist and elegant, with two water-resistant, zippered torso pockets above harness-line, low-profile cuff closures and our new Touch Point System(TM) - embedded cord locks in the hood and hem for quick adjustment without opening the jacket. Sonic-welded seams reinforced with micro-stitching (patent pending) reduce seam bulk and weight while optimizing strength, and the helmet-compatible, 2-way-adjustable hood with laminated visor affords visibility in bad conditions. Full-reach gusseted underarm panels allow overhead mobility.
