Floats like a butterfly and the single radius sidecut stings like a bee. A unique experience for those who seek the moment. Features a tapered mild swallowtail shape and big square nose letting you effortlessly float. Take this unpowered flight with the Backseat camber profile and be drawn into the vortex of a single radius sidecut that reaches far into the contact points of a fully cambered tail. Predictions of the effects of both observed flow patterns and pressure distributions were consistent with actual forces and moments measured using the force balance. Enter the Portal!


  • Backseat CamRock - The design places rocker in the nose and a slight amount in the tail with positive camber in between. This setback design delivers camber stability and control between the feet and in the tail, with the added float and maneuverability of the rockered nose.
  • Carbonbon - Pure carbon fiber slabs are placed in a cross pattern under the inserts between the base and the core to enhance responsiveness, pop, torsional stiffness and to amplify foot movement.
  • Tri-Ax Fiberglass - Triax fiberglass is the time-tested classic. It features a three-way weave of premium fibers with strands running at 45-degree angles. It provides superior pop, consistent torsional flex, and more overall response.
  • Lightweight Woodcore - Crafted with light density paulownia for lightness, polar for responsiveness and hardwood beech stringers along the edges to increase core durability, pop, and protection from edge impacts.
  • Bi-Ax Fiberglass - Biax fiberglass is a two-way weave of fiberglass with strands running every 90-degrees. It's more forgiving, easier to flex and highly versatile for all terrain types.
  • Sintered NHS Race Base - High performance ultra-high molecular sintered race base with the addition of graphite. This is a premium base material with the best gliding characteristics and optimal durability.
  • Diamond Stone Finish - Slash adds a slight diamond-structured stone grind to the base to maximize glide and optimize durability. It eliminates the slow, suction cup feel that comes with one-dimensional base finishes.
  • Singular Sidecut - A predictable and powerful sidecut with a single radius that makes for consistent turns. It’s ideal for intermediate and advanced riders who already know how to carve a turn, like to ride fast, and desire strong edge hold.
