2024 Duotone Sky Air

The 2024 Duotone Sky Air is an inflatable wing foil board built for portability without sacrificing on-water performance. Produced by Duotone, one of the established names in wind and wing sports, the Sky Air sits in the brand's lineup as the travel-friendly entry point to wing foiling. It uses Double Layer Light Technology construction with welded rails, producing a board that packs down into a wheeled backpack yet inflates to a noticeably stiff platform. A carbon plate runs from the foil mount area to the front foot position, integrating the foil tracks and a carrying handle into a rigid stance zone that adds stability where it matters most. A silicone rail edge along the tail area helps the board release cleanly from the water surface during takeoff, addressing a common weak point of inflatable designs.

The 2024 Sky Air is offered in three sizes. The two smaller models — 5'5" at 105 liters and 5'9" at 125 liters — mirror the footprint of Duotone's hard-shell Sky Free boards. The largest 7'2" model at 215 liters adds side fins (US-Box) and a rear fin (Click-System), allowing it to be used as a non-foiling wing board for riders still learning upwind technique before their first foil takeoff.

The Sky Air targets beginner to intermediate wing foilers who value easy transport. The 7'2" / 215-liter size suits heavier or newer riders who need high stability and the option to practice wing handling with fins before committing to foil takeoffs. The mid-range 5'9" / 125-liter board fits intermediate riders progressing into freeride foiling, pairing well with higher-lift foils in the 1,200–2,500 cm² range. The compact 5'5" / 105-liter option serves lighter or more experienced riders who want a packable foil platform for travel.

Because the entire package — board, pump, straps, and bag — fits into one wheeled backpack with room left for a wing and foil, the Sky Air is aimed squarely at riders who fly to their sessions or lack dedicated gear storage. The inflatable format also removes ding anxiety, making it a practical choice for rocky launches or boat-based foiling trips.

Within Duotone's 2024 wing board range, the Sky Air is the only fully inflatable option. Riders looking for a rigid freeride board at a similar price point would step into the Duotone Sky Free, which shares comparable outlines in the smaller sizes but offers the stiffer ride of composite construction. Above both sits the Sky Style for more performance-oriented foiling, and the Sky Style SLS at the top of the range with premium carbon layups.

For 2025, Duotone evolved the concept further with the Skybrid Air, which blends elements of the Sky Air and the brand's downwind boards into a single travel-oriented platform. Riders cross-shopping other inflatable foil boards may also consider the Fanatic Sky Air or the F-One Rocket Air, both of which target the same travel-and-learn segment with similar inflatable-plus-carbon-plate construction approaches.
