Mountain Hardwear

Nitrous Vest - Men's

For years, down has been known for two things—unparalleled warmth when dry and complete uselessness when wet. Mountain Hardwear solves the saturation issue with its water-resistant down, used in the Men's Nitrous Vest. Incredibly lightweight and packable, the Nitrous will serve as your go-to layering piece for your next hike or your next ski vacation.

The Nitrous vest's face fabric is tough 30D nylon ripstop fabric. This wind-resistant fabric is soft and smooth to make layering easy. Mountain Hardwear then insulated the vest with its Q.Shield 800-fill water-resistant down. The down fibers are permanently infused with a water-repellant, so it maintains its loft and its insulating properties when wet. The Nitrous' dual hem drawcords seal out drafts to keep you warm in high winds, and the jacket stuffs into its own pocket for the minimum possible pack size when not in use.
