Montbell Women's U.L. Down Vest

What keeps you warmer, a T-shirt or the MontBell Women's Ultralight Down Vest? If you guessed the former, remind us not to plan a winter camping trip with you. If you picked the latter, you are correct; and yet this super-warm vest doesn't occupy any more space in your pack, or weigh any more, than your average tee.

The Ultralight Down Vest is packed with 800-fill goose down, which is lightweight and lofts easily after being compressed. While warmth is this jacket's hallmark, it also does a nifty job at keeping wind and moisture out. The 15D Ballistic Airlight nylon shell ensures durability without sacrificing weight, and Polkatex DWR coating keeps out all extra moisture trying to sneak in (it's rated to maintain effectiveness for 100 washes). Single-quilt construction reduces weight and stuffs easily into your pack or pocket. Can your tee do that? Nope, it can't.
