STX Air WindSUP Board

STX Air WindSUP (iWindsurf) isn’t just a standard SUP board with an added deck thread – it’s a dedicated inflatable windsurf platform made for freeride. The board is designed to deliver an experience as close to a classic hardboard as possible. That means easy handling, stable starts, and predictable control across a wide range of conditions. Paddle out on those perfectly glassy days, then attach your sail to cruise as soon as the wind picks up.

The board is packed with real windsurf features, including footstraps, a dedicated mast base plate, and an innovative Railsaver edge on the bottom that ensures clean water release, better acceleration, and earlier planing. Thanks to the ultra-light and extremely stiff FXL construction (Fusion Woven Dropstitch) and the double-layer, hyper-glued rails, flex is minimized significantly, giving you an incredibly stable platform—even when the board is loaded with the weight of a full windsurf rig.

• FXL Technology (Superlight & Stiff): Woven dropstitch construction that makes the board extremely light while achieving unmatched stiffness when inflated.
• Real Windsurf Footstraps: Comes with adjustable windsurf footstraps and integrated inserts so you can lock your feet in and push for higher speeds as your confidence grows.
• Honey & Gator Grip Deck Pad: The smart deck pad is divided into different grip zones, making it easy visually and by feel to find and repeat the perfect foot placement.
• Dedicated Mastbase Plate: Reinforced base area specifically designed to handle the constant forces from a sail without stressing the board’s inner core – ideal for frequent use and windsurf schools.
• Railsaver Edge: A sharp edge profile at the back of the board’s rail ensures water releases cleaner, reducing drag and helping you get up on plane faster.
• US Fin Box System: The universal and widely used fin box system makes it easy to swap or upgrade fins based on local conditions. Fins are included in the package.
