JIMMY STYKS™ SUP boards are constructed of high quality EPS and epoxy. This combination of materials gives our product strength while remaining as light as possible. All of our SUP boards (with the exception of our all-carbon fiber/stringerless models) feature a durable three layer 6 ounce epoxy glass deck and two layer 6 ounce epoxy glass bottom over 2 lb/ft² EPS core. A final protective clear coat is applied and polished to give the finished product a beautiful luster.
