Rev’it! Sport’s Climate jacket is a technical mid-layer designed to be worn under your protective motorcycle jacket, or in my case, all the damn time, everywhere I go. Nylon rip stop fabric (blue), makes up most of the body and insulates very well, while blocking wind when wet or dry. Polartec Alpha fabric lines the inside of the arms, body and collar to insulate incredibly efficiently, but also quick-dry if they happen to get wet. Breathable sections (black) in the sides and underarm are softer with more stretch and very breathable allow hot air to escape.
