The North Face ThermoBall Vest

Called "the breakout alternative to down", The North Face's Thermoball™ is about as innovative as insulation gets. The North Face Thermoball Vest not only has insulation equivalent to 600-fill down (mmm, toasty), it can stand up to moisture and is super light and stowable in its own pocket. Your core will be grateful for an abundance of heat as you camp, hike or just take a stroll around town in the coldest of conditions in The North Face Thermoball Vest.
