This sleek and professional-looking coach windbreaker jacket is made from high-performance 33D nylon that’s serious about keeping water out. Its fabric has a special Level 3 waterproof coating on the outside, which means rain just rolls right off instead of soaking through and making you wet. But it doesn’t end here, there’s a smart PU coating on the inside of this windbreaker-style jacket that does two important jobs: it stops water from getting in (it can handle water pressure up to 10,000) while still letting your skin breathe (with a breathability rating of 5,000).
