The PRO Vest is designed to carry everything you need, but is very light and breathes well for comfort. It is built of light, abrasion-resistant nylon with a DWR coating. The fitted design is built to conform to the body. The shoulders have a lofted spacer mesh of nylon and spandex. There are 18 pockets—10 exterior, 6 interior, and 2 rear ergonomically designed with new materials to provide organization coupled with smooth workflow on the water. The two lower main pockets offer compression-molded construction that add rigidity. The upper pockets are medium size, both with Orvis custom hideaway tool port underneath two fly-drying patches. The rear pockets offer a large pass-through game-style pocket under a full-zip rear pocket with mesh panel divider. Other features include multiple daisy chain gear loops, elastic loops to attach tippet bars, an adjustable closure that slides vertically for a custom fit, padded collar for comfort, internal webbing hanging loop, and a tri-ring net holder centered on the rear yoke.
