Rethinking the puffer design. Made with recycled materials, the synthetic insulation in the Nike Sportswear Jacket offers high-loft warmth and a classic puffer look. Zippered pockets offer secure storage for your keys and phone while a hooded design offers extra coverage and warmth when the temperatures really start to drop. A woven polyester fabric has a soft, smooth feel. The zippered pockets store your stuff on the go. The fleece cuffs pull down over your hands to keep them warm and covered. Synthetic insulation recycles plastic waste to create a sustainable alternative to down. 100% Polyester.
