Stay under the covers? No way. Not with this adidas by Stella McCartney jacket on your back, the perfect response to cold-weather cardio or a chilly morning commute. Made with a super-soft material, it keeps you warm but cools you off with HEAT.RDY — innovative technology designed to keep you going when things heat up. Side zip pockets offer convenience, and thumbhole cuffs keep the fit in place. A two-way zipper from top to bottom lets in fresh air wherever you need it most. You've got this, whatever this is.
