Patented Swim Monofin

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! Although our monofin fits comfortably and securely, you can also remove it quickly and easily with a light tug and a kick.

Safety is our #1 Priority

Safety is our #1 Priority

  • Breathable Fabrics Won’t Trap Air
  • Open Ends for Easy Access to Feet
  • Quick Kick-off & Swim Out Design
  • No Straps, Zippers or Velcro

Safety is our first priority at Fin Fun! We’ve designed our monofin with the highest level of safety features, setting it apart from other monofins that force you to “strap” your feet and/or ankles into the monofin. Our monofin is designed to stay securely on your feet, though it can be quickly removed in or out of the water.

Lightweight Monofin

Lightweight Monofin

  • Weightless in Water
  • Weighs Only 1lb
  • Neutral Buoyancy
  • Open Monofin Fits All Foot Sizes

Crafted from dive-grade neoprene that houses a highly advanced polypropylene insert, our monofin is the perfect combination of strength and rigidity while being extremely light and flexible. This gives the monofin and mermaid tail its incredibly realistic shape and mesmerizing motion for an unforgettable swim worthy of your wildest dreams! Plus, its neoprene sleeve accommodates feet of virtually any size for a comfortable swimming experience. Say goodbye to bulky, painful, or unsafe straps!

Breathable Fabric, Realistic Design

Breathable Fabric, Realistic Design

  • 4-Way Stretch Fabric
  • Color-Safe in Salt Water & Chlorine
  • Custom Printed, 3D Designs
  • No-Bulge Ankles

Fin Fun mermaid tails are custom printed 3D designs, made from breathable, 4-way stretch swimsuit fabric that allows air and water to pass right through. Some people worry about the tail trapping air and making the legs float up--this is not possible in our mermaid tails due to open ends and breathable fabric.

Give the Best Gift Ever!

  • A mermaid tail gets the kids off the couch and outside to play. No batteries or electricity needed!
  • Kids can pretend to be The Little Mermaid with a toy that encourages imaginary play and exercise.
  • Wearing a mermaid tail allows swimmers to express their individuality in a unique way that often gets positive feedback from others. Mermaids attract excitement wherever they go!
  • Mermaiding expands upon swimming skills (like the “dolphin kick”) and encourages users to live an active lifestyle.
  • The Fin Fun “unboxing” experience is truly exceptional. We believe that everyone deserves to dream and we try to make your experience a “dream come true” from the moment you receive your package.
