MontBell Ultralight Down Vest - Women's - $118.95

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. Stuffed with ultralight goose down, this vest not only turns up the heat under your shell, but does an admirable job of blocking wind and rain when worn on its own. - $118.95
