The Cosmic Pro SO H2O Jacket keeps water from getting in – but it’s also brilliant at letting perspiration out. One of the big things when riding in the rain. It’s 20, 000mm waterproof, fully seam-sealed & treated with Teflon® for total water, dirt & oil resistance. Then for breathability it’s engineered with our signature 37.5® technology that uses active particles to accelerate evaporation, making this jacket 20% more breathable than its leading competitor. It’s super streamlined too (because no one wants their jacket flapping in the wind like a plastic bag). The close-fitting Pro Fit construction has been carefully tailored to hug your body & match your riding position. While the advanced back tail keeps tyre spray at bay too.
