JL Racing Sequel Turtleshell vest is designed for rowing and cold-weather workouts, featuring a Thermo Roubaix front for warmth and a waterproof Hytrel back to keep you dry. This hi-viz technical vest offers a snug fit with full range of motion, a tall collar with a neck zipper to block wind, and a long tail that floats above rowing tracks to keep the lumbar region warm. Functional details include a side zipper for easy transitions on the water, a chest pocket sized for rower essentials, and armholes cut to prevent chafing at full reach.
