With a Crescent Tail, Channels, Single Stringer and Wave-Plank Polyethylene Core, the Custom X XPE is an excellent all-around bodyboard. The XPE is handmade in the USA and packs a ton of features into an affordable price. The Custom X XPE features a Wave-Plank PE, or Polyethylene, core. This core type is heavier and works well in both water types, but even better in colder waters. The XPE features a tight-cell deck material for added durability. Top that off with a single graphite stringer and you've got a board that offers some good flex and great durability in this price range. 60/40 rails allow this board to maneuver quickly and turn fast. A Surlyn® slick allows this board to glide on the water. Surlyn® is well known as the best slick material currently offered on the market.
