I dinint really like it that much but my son did . and my daughter loves her fin fun mermaid tails

Why only advertised for boys?


I am a girl and I bought this. I like it and I also have a mermaid tail so sometimes I am a mershark(mermaid/shark combination). I have a question. Why is this only shown on boys? I would really appreciate it if you showed it on a girl at least once. I am also disappointed that is in a "for boys" section now. Can you please show a girl in the shark fin or a girl mershark? I really would like you to (please reply)

cool product


Initial thoughts are that it appears well built and pretty solid. Time will tell. All my scuba buddys thought it was very cool (I have it straped to my air tank) would like to see gray as a color option. The straps are a little small for me, I am 6'1' about 170lbs. Fits the tank nicely though. <br> <br>Fin Fun Says: Now new and improved straps allow for more room.

Shark VS Mermaids in our family!


When my 2 girls each got a tail, we didn't want our son feeling left out of the aquatic fantasy fun! I was gonna get him a black tail, but my husband wasn't having that... lol This shark fin was the best choice! He's not the strongest swimmer, so we are holding off on the monofin for now. He was so excited about this shark fin!!! And what brother doesn't like to make his sisters scream at the pretend threat of eating them?! LOL We had to continuously adjust the straps in the beginning, so we made it just a little extra tight, problem solved. He says its comfortable, light, and loved the props he was getting from other kids at the pool party! He wore it over a swim shirt, so I'm not sure how comfortable the straps would be on bare skin. They seem soft enough though! All in all, worth every penny!



Wow, i showed my brother your website and i told him there were shark fins, and now he really wants one! i'm planning to buy him one for his birthday, as a surprise, by the way i am a 9 year old girl.

So cool..but the arm straps are too small for bigger kids


My son is 11 and tall and really wanted this fin. I ordered it for him but the arm straps were uncomfortably small especially for kids with a longer torso. There was not enough adjustment and length in the straps. He was so very bummed. We gave it away to our neighbor's younger son who is 6 and he loves it. <br> <br>Fin Fun Says: Now with new and improved straps allow for larger reach.



I got this for my brother's birthday and he loves it. The straps are really comfortable for him. He is just learning how to swim so this is perfect because it's light. HE LOVES IT!!



My grandson really likes his sisters tail. But he wants to be a MERMAN. He will be so thrilled in March that for his birthday he not only gets a tail but a fin to go with it! His imagination will go wild.
