Any checklist of alpine dash essentials would be incomplete without a rope, a skeleton rack, and the Patagonia Women's M10 Jacket on your back. Built for those who thrive on technical climbs in full alpine conditions, the M10 is a study in minimalism the lightest hard shell Patagonia makes. Consequently, it's managed to become a no brainer favorite amongst Patagonia's climbing ambassador community. The soft, pliable H2No Performance Standard nylon ripstop fabric yields surprising durability for its weight and protects against monsoon season precipitation and summit ridge gusts. Patagonia kept the design simple and low profile by eliminating pit zips, yet it maintains the traditional alpine hardshell silhouette with its harness compatible hand pockets and a chest pocket that ultimately doubles as a stuff sack with a reinforced clip in loop. Details include sonically welded seams with the narrowest possible tape, watertight zippers, a microfleece lined neck and chin, and cuffs that adjust with minimalist hook and loop closures. A single pull adjusts the helmet compatible hood, a laminated visor offers a personal canopy, and a drawcord hem blocks out the rather unsavory backdraft that has a propensity for sneaking up on you when you least expect it.
