TUSA HyFlex Switch Fins

The TUSA SF-0104 TUSA HyFlex Switch Fins are ideal for casual divers seeking a quick and effortless response to their movements. The PuRiMaX “Polyurethane Blade System” offers a snappy response, making it effortless to kick and propel through the water.

Furthermore, the unique “Vortex Generator” reduces water resistance, enhancing the stroke’s ease. Lastly, the 20-degree Angled Blade Design is offset by a large vent hole between the blade and foot pocket, facilitating kicking near the toe surface area.

The TUSA Hyflex Switch’s exceptional multi-compound foot pocket not only enhances power transfer to the fin blade but also provides an incredibly comfortable and snug fit, making it one of the best on the market.

To complete the package, the Universal Bungee Strap offers extraordinary comfort with three adjustable settings on each side. Additionally, you can easily detach the fin blade from the foot pocket, transforming it into a compact and lightweight travel-friendly package.

Switch Fin Technology

POWERED BY PURIMAX

The fin blade is made of top-quality Polyurethane material that provides a quicker response to movement over rubber and plastic fins.

VORTEX GENERATOR

Six (6) performance ridges positioned behind the blade vent reduce resistance, creating a smoother and more efficient kick cycle.

ANGLED BLADE DESIGN (A.B.D.)

The Angled Blade Design accommodates this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.

BUNGEE STRAP

The heavy-duty elastic fin strap provides easy donning and doffing of fins. The quick adjustment accommodates five (5) adjustable positions.
