Very Good Vest from ON; REI Fulfillment Less So
Very nice vest. Made of light, high-quality materials with plenty of perforations for sweat evaporation. Just size up. My chest is 39-40 inches, so I ordered a medium but it was too tight around the rib cage. Had to return it for a L. Also, before your first run, be sure to remove any unused bungee cords, especially the ones under the arm pits. They were flapping around and hitting my arms. Quite annoying. Final comment is about REI fulfillment and not the ON product. Product arrived on time, but the product looked like it was used. The color was a little dingy, the item was wrinkly, and it wasn't in the same packaging as the original M size that i returned. Please do better!
