SF-9900 (Extra Large)
- High performance Multi-Flex Blades
- Double layered construction using T-Bondex and flexible elastome resin
- TUSA patented easy-to-adjust strap with quick release buckles
We studied dolphins to create unique swim fins that provide more thrust with less effort. Our unique construction channels the water when you swim, much like the whip-like motions of the dolphin. With TUSA IMPREX fins you glide through the water with less effort and more comfort. TUSA also accommodates individual needs by providing these patented fins in three sizes: Regular, Small and Extra Large. All sizes feature TUSA's unique multi-flex blades for maximum propulsion with minimal effort.*SF-9900 is available in Black(BK) and Cobalt Blue(CBL).
Features of SF-9900, SF-7700 and SF-8800
The IMPREX fin blade itself is made of distinct materials. The outside ribs are made from stiff material and between the ribs you'll find softer, more pliable material. The middle ribs are more compliant than the outer ribs, allowing the fin to effectively channel the water while you swim, similar to the whip-like motions of the dolphin.
|Hydrodynamic channeling action reduces leg fatigue while increasing power.|
