It's five o'clock somewhere, which for some folks means buying double rounds of winter stouts and for others it's a whole other kind of happy hour strictly meaning it's time to lace up those running sneakers and blaze trails out the door, regardless of whether or not Old Man Winter has settled in for the season. So whether you're running through the glazed over sidewalks of Boston or rallying through the frosty tipped Bonneville Shoreline Trail in Utah, the Nike Women's Aeroloft 800 Vest keeps you coming back for more. Crafted with a streamlined, sleek Dri FIT exterior and cozy warm 800 fill goose down, this vest is built specifically for maintaining core warmth throughout the course of your cold weather fitness adventures, without weighing you down or restricting movement. The water repellent finish assures a little extra safeguard against wayward weather should the skies unleash some unexpected flurries. However, the strategic laser perforations between the baffling permits excess body heat to escape and ultimately encourages optimal body temperature regulation while the rear zippered pocket and attached hand strap allows you to easily stow and carry the vest should you begin to overheat.
