The Assos sJ.climaSchutz jacket is the most technically advanced and packable rain/wind jacket available, made out of a unique microfiber, coated with an active elastic, breathable membrane. As water contacts the jacket, the fibers expand to keep moisture out, and as it dries, the fibers contract to allow better breathability. Ventilation is further enhanced with breathable panels on sides and arms. Rear vents provide easy access to your jersey pockets, plus the inner jacket pocket. Wide, ergonomic wristbands allow a perfect fit under the gloves. Easily compressed in a jersey pocket.
