Monofin Infographic

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 polypropylene 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!
