A seriously tough, expedition-ready shell, the Mammut Women's Nordwand Pro HS Hooded Shell Jacket is for chicks who'd rather be duking it out with Mother Nature high in the alpine. They say the key to a good defense is a good offense, and the fully taped, three-layer, Gore-Tex Pro shell puts up a solid fight against the harshest of elements.Mammut's High Reach and Vertical Motion technologies let you maneuver your way through the crux with unrestricted mobility, and the external chest pocket is backpack-compatible so it's easy to reach for a candy bar when you need a little energy boost. The hand pockets are compatible with your climbing harness, and the powder skirt can be easily removed if you're not travelling in super deep snow. Flip up the helmet-compatible hood when the winds pick up, or open up the underarm zips when you're working up a sweat and need to dump heat quickly.
