Mizu™ fuses 7.4-ounce Performance Denim with Japanese Teijin Octa® fleece lining. It's an unlikely but amazing combination of classic Americana style and modern technology. Ripton's most feature-rich garment to date, this anorak has a large hood, adjustable with a drawcord, articulated sleeves, and a zipper opening on the left size. The off-center placket snaps up to your nose. Or if you're hot, it opens halfway down for ventilation. A vented back yoke also promotes airflow. Octa fleece technology is built on fibers with eight facets, rather than a standard round fiber. This creates a yarn with hollow air pockets. It's warm and breathable without the bulk, because air is the best insulator. Unisex sizing. Kody is 5'9", 170lbs, and Tizzy is 5'7" 130lbs; both are wearing a size Medium. Our impression is that this runs true to size for a unisex or men's sized jacket.
