The Monofin Jr. fits our youth / child sizes 6, 8, and 10 mermaid tails perfectly!
For tails sizes 12 and up, you will need a Monofin Pro.
Fin Fun’s Original Monofin features an ultra-comfortable design. Our high-quality neoprene encases our advanced, flexible, and strong plastic insert while a second layer of neoprene reinforces the tips for a more durable monofin. A stronger monofin helps keep your mermaid tail secure and may help prevent wear on your mermaid tail. Our innovative design holds your feet comfortably without pinching, chaffing or straps. This monofin may also be used without a mermaid tail to swim in a fast and exciting “dolphin kick” motion. We believe our Fin Fun Monofins are the safest and most comfortable on the market!
In fact, it is so good we have the U.S. Patent (#9162110) on our unique monofin design. When you use it yourself you will be amazed!
