Do you want more stability, grip, and comfort while mermaid swimming? The Mermaid Sisters Pro Monofin is our updated premium monofin, designed for a better fit and more control in the tail. Thanks to the new centerline, the feet stay better separated, providing extra stability and helping reduce shifting while swimming.
The updated monofin is made from strong wetsuit material, making it sturdier and longer-lasting. The inner socks have also been improved: they are stronger, more comfortable, and feature a sole with an anti-slip coating for extra grip and support. This makes the monofin more stable during swimming while still being easy to put on and take off.
This premium monofin is ideal for swimmers seeking more control, comfort, and durability during mermaid swimming.
Note:
Small monofin is suitable for mermaid tails size 4.
Medium monofin is suitable for mermaid tails sizes 6, 8, 10, and 12.
Large monofin is suitable for mermaid tails sizes XS, S, M, and L.
