When the temperatures plummet and we start to see frost on our morning commutes, it makes us eager to reach into the back of our kit drawers for Sugoi's RS Zero Long Sleeve Jersey. With a tailored fit and two hardworking proprietary fabrics providing warmth without bulk, the RS Zero is a welcome addition to any kit from the first, crisp fall climbs all the way through late winter's chilly base miles. At the back and sides, you'll find Midzero, which is used for its excellent breathability and moisture wicking properties. This soft medium weight fabric features a brushed inner layer that pulls moisture away from the skin, creating a warm and dry micro climate, while the outer layer has a stronger, abrasion resistant face. It also provides full motion stretch without adding bulk, so you're able to layer the RS Zero or wear it alone. At the sleeves and chest, Sugoi opts for the lightweight Firewall 180 to add superior wind resistance to the Zero RS without sacrificing breathability. A lightly brushed interior assists with thermal regulation, while a PU coating keeps the wind and light rain at bay. Additionally, Firewall 180 stretches quite well to provide an excellent range of motion while preserving a race ready fit. A full zip front ensures an easy on and off and allows for on the fly temperature adjustments during climbs. The three rear pockets expand easily to create extra storage space for a shell, and the signature hem gripper keeps the jersey from riding up and exposing your skin to the elements. As a finishing touch, reflective elements help you stay visible on the road.
