STX iWINDSURF WS 280 RS WindSUP Board

STX iWINDSURF WS 280 RS is a true inflatable windsurf board designed for beginner and intermediate riders who expect high stability, paddling comfort, and solid performance. With dimensions of 280 × 86 × 15 cm and a volume of 280 litres, this model performs very well during learning sessions, family use, and first attempts at planing.

A true inflatable windsurf board

WS 280 RS is not a classic paddleboard, but a board designed specifically for windsurfing. It is equipment that offers more dynamic riding, better control under sail, and the ability to get on the plane. It is a very good choice for riders who want to improve their technique and get more enjoyment from active time on the water.

Stability and performance for beginners and intermediate riders

The board was designed for riders looking for gear that is stable, predictable, and forgiving, while still allowing clear progression. The 86 cm width provides a lot of confidence on the water, while the compact length keeps the board easy to manoeuvre and more dynamic than larger, purely recreational models.

FXL technology and reinforced rails

The board is built using FXL (Fusion Double Layer X Light) technology. This is a lightweight, woven, and welded construction in which two PVC layers are joined without the use of glue. Combined with additional Double Layer Rails reinforcements, it provides very good stiffness, low weight, and high resistance to deformation. This construction results in performance close to hard boards while maintaining the advantages of inflatable equipment.

Railsaver and 3 US-Box fins

The 2025 version features the Railsaver system, a specially profiled rear edge that improves water release and makes it easier to get on the plane. Under the board there are 3 fins in the US-Box system – two rear fins and one central fin. This setup provides very good control, stability, and confident tracking while sailing with a rig.

Deck ready for active riding

The deck is finished with dual-colour EVA foam in a Honey Grip and Gator Grip texture, providing good traction and comfort when positioning your feet. The board is also equipped with 4 neoprene adjustable footstraps, which can be mounted in different configurations depending on riding style and skill level.

A mobile windsurfing set

Despite its sporty character, the board remains easy to transport and store. The whole set fits into a compact wheeled backpack measuring 90 × 42 × 25 cm, making it easy to carry the equipment without the need for a roof rack. It is a very practical solution for people who want a mobile windsurfing set.
