Patented Swim Monofin


Our exclusive monofin is the most comfortable, safe, and realistic mermaid monofin in the world. You will experience a new level of mermaid power as you glide through the water with the best mermaid monofin available! With our patented design and dive-grade neoprene cover, there is no other monofin like it. It fits so naturally you can hardly see your feet and ankles inside, which helps you look like a REAL mermaid! See our safety video showing you how to easily remove monofin while swimming.

Dive-Grade High Quality Neoprene

Fin Fun’s Blue Trim Monofin offers a streamlined, yet stylish look with bright blue accent stitching and the same ultra-comfortable design as our traditional monofin but with colorful flair! High-quality neoprene encases our advanced, flexible, and strong plastic insert while a second layer of neoprene reinforces the heel piece and 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, chafing, 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!
