Bio-Fin XT

Features & Benefits

Adding synthetic material is a quick annd inexpensive method for stiffening a fin. We chose to produce the XT in 100% rubber. Tests have proven that rubber will outperform any synthetic option.

• Increasing the durometer to 75° rather than changing base material creates a stiffer blade that retains a high degree of the comfort and performance of our original bio-fin pro.
• Higher durometer rubber provides the feel and weight of a more traditional fin
• Works as well or better than paddle fins with any choice of kicking style
• Split fin design allows for increased maximum speed and reduced fatigue
• Consistently rated as the fastest fin in the water
• Instant turning and pivoting on a dime
• Increased control and added leverage for technical divers
• Reduced air consumption
• Increased bottom time
• Color: metallic black
