The matte outer fabric offers protection from rain, while the lining provides temperature regulation so you can hit the snowy streets with confidence. Offering an alternative to down without compromising on design or warmth, our PRIMALOFT Thermoplume fill is made from a water-resistant fiber blend that provides insulation, weather protection and compressibility. It's made up of small tufts of silky, feather-like fibers, and the Nike Storm-FIT technology protects you from wind and rain for lasting comfort in extreme conditions. PRIMALOFT insulation keeps you warm and dry in cold, wet weather, so you can keep exploring your city when temperatures start to drop.This herringbone design is inspired by the 1978 Windrunner track jacket, famous for its unique, deceptively simple design.
