The Men`s Alpine Wind Jacket by Patagonia is a super lightweight, lined windshirt for alpine pursuits; this jacket is great for use as a layering piece or a light outer layer. On high ridges, steep ice and anything alpine, this jacket serves as a true `best of all worlds` staple. It excels as a stand-alone shell for blustery rock climbs, cool-weather trail runs and high-output ski tours. And then, when conditions have you ice and alpine climbing, it functions as a lightly insulated windshirt on the approach, as well as a frictionless midlayer when it`s time to bundle up and tie-in. The polyester ripstop shell with a Deluge DWR (durable water repellent) treatment sheds snow and blocks wind, while the smooth, lightly brushed hanging mesh liner wicks moisture, dries fast, and doesn`t bind to your baselayers. Superlight stretch-woven underarm panels enhance breathability and allow for unimpaired arm motion, and zippers close the three pockets (two hand, one chest). A drawcord hem, elastic cuffs, a heat-transfer reflective logo and a regular-coil, center-front zipper with DWR finish round out the features. Recyclable through the Common Threads Recycling Program.
