Finis Aquarius Mermaid Monofin


SKU: Categories: , Tags: , , ,


The Aquarius fin is a fantasy monofin designed to help young swimmers develop a balanced dolphin kick and confidence in the water.  Like the Mermaid monofin, the Aquarius fin teaches similar concepts for swimmers ages 10 and up.  The broad surface of the fin reinforces an efficient dolphin kick and builds leg and core strength.  Strategically placed holes throughout the fin and foot pocket allow for greater manipulation in the water as well as higher speeds for strong swimmers.  The Aquarius offers some adult sizing, as well as added durability and comfort.
