The Gore Wear C5 Gore-Tex INFINIUM Thermo Jacket may earn its name from hurricane wind scales. The C5's windproof and water-resistant membrane fend off heavy winter elements to keep you as comfortable as a kitten on a ranch porch in the summer, even if the weather looks more than a little hair-raising. Soft fleece runs on the interior to trap body heat in during cold weather riding, while Gore-Tex Windstopper blocks out wind that would otherwise penetrate lesser fabrics. The result is a fully mobile micro-climate that breathes well during intense riding sessions to keep your base miles training and racing calendar in top shape.Gore Wear uses a slim fit to cut down on fabric flap at speed while still supporting the traditional three rear pockets so that you won't have to unzip the front to find jersey pocket snacks. The rear zip pocket -- which is becoming a welcomed standard on modern cycling tops -- secures belongings and keeps them dry. An extended tail prevents rear wheel-spray from soaking your lower back and glutes, and stretch inserts are on board for freedom of movement in cycling-specific positions.
