Made my kids day!!! Will say that we had to size up from the kid version to the adult. She’s a size 4.5 ish. But we had a hard time getting the kid size on so switched to the adult and it’s great. Seems durable and honestly, she likes it so much and it’s so neat we’d buy another even if this one does wear out. Bought a tail cover from another brand on desertcart that fits over this perfectly, so in the water she looks great! Had her practice getting it off in the water and she was able to easily and very quickly, which made me happy. Review: 10/10 - Amazing! My little one LOVES this tail. We had to buy and return a couple of duds before we found this one. Great quality. Fits her feet perfectly and isn’t slipping or popping off. ## Features - Glide through the water with more speed and less effort with this stylish and unique monofin - Engineered Fin Fun monofin creates a natural mermaid motion to help strengthen your core - Dive-grad neoprene cover with comfortable foot pockets – No Painful Straps – and an unbreakable polypropylene fin - Designed with safety in mind with neutral buoyancy and fast, hands-free removal - Hand wash only ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07482KCXB | | Best Sellers Rank | #7,388 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #16 in Swimming Training Fins | | Brand | Fin Fun | | Brand Name | Fin Fun | | Closure Type | Pull-On | | Color | Blue Trim Black | | Customer Reviews | 4.6 out of 5 stars 3,327 Reviews | | Fit Type | Regular | | Item Dimensions L x W | 17.5"L x 18.5"W | | Manufacturer | Fin Fun | | Manufacturer Part Number | MF-05-JR | | Material | Neoprene | | Material Type | Neoprene | | Model Number | MF-05-JR | | Product Dimensions | 17.5"L x 18.5"W | | Sport | Swimming | | Sport Type | Swimming | | UPC | 818033024852 | ## Images ![Fin Fun Mermaid Monofin - Swim Fin for Kids - Swimming Flipper with Comfortable Foot Pockets - Snorkel & Water Accessory Made w/ Dive-Grade Neoprene - Image 1](https://m.media-amazon.com/images/I/71bhLAAuIuL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What kind of warranty do you offer for the product? I'm scared to spend triple of the regular price ones and would last 2 times as some costumers say** A: I'm not sure of the warranty, I can attest to the quality. My 12 year old granddaughter has used it several times and is holding up well. **Q: Will the monofin size jr (6-11) fit into the swin fin child size 10 swimwear?** A: Yes **Q: Is it supposed to be real tight and hard to get your feet in? Says it fits up to size 7.5 and my kid only wears a size 4.** A: My daughter wears a size 4, she's a tween, and she cannot get it on, the youth/junior size is unusable. She could force one foot in, but couldn't get both feet in. We will be returning it, and maybe getting the adult one. **Q: Will this fin fit a size 5 shoe womans** A: The Monofin Jr. will fit youth to adult sizes up to size 7.5. The Monofin Pro will fit youth sizes up to a men's size 13. The important thing to consider is mermaid tails size 6, 8, and 10 are all made to hold the Monofin Jr. The mermaid tails size 12 and larger are made to hold the Monofin Pro.

Fits her feet perfectly and isn’t slipping or popping off. ### ⭐⭐⭐⭐⭐ Fun Pool Toy *by D***A on July 3, 2023* I wasn't sure I got the correct product and had to measure it. It looked small but it measured the correct width for the adult size. This fin went to a pool party and got stress-tested by me and three young boys. I think my feet were the smallest. The boy with size 9s had some difficulty getting his heels in. He gave up but was still able to use it even though it wasn't correctly worn. The ankle openings were very tight. It doesn't make any difference what size your feet are. If you can get your feet into those ankle openings there is nothing else there to hold it on. Too tight and it can't be removed in a hurry. Keep that in mind. He had it so the openings were around his feet with his heels out and swam with it. He had the same fight the rest of us did getting it back off. It's a bit of a learning curve, but if you can tread water you can do it. It's easier to remove if you can stand in the shallow end. The cover of the fin is neoprene and just a bit thicker than swimsuit material. It held up well for the party and fit me fine after all my poolmates had a turn with it. The tips of the fin rubbed the pool walls and bottom and showed holes, not just fuzz, when we got out. Even I couldn't avoid rubbing it against the pool walls and bottom. They didn't affect its use, but could eventually open enough to no longer hold the plastic fin inside. If you sew, you could repair that with swimsuit material patches. Over all, it was a fun pool toy and I'm glad I bought it. I left it with the boys since they swim more often than I do. We all had fun swimming like fish. ## Frequently Bought Together - Fin Fun Mermaid Monofin, Swim Fin for Kids and Adults - FOLOEO Mermaid Tails for Swimming, Mermaid Swimsuit Costume Set Bathing Suits for Adult & Teen Sizes - Choadam Princess Costume Adult Women Men Bikini No Flipper Beach Costumes Swimsuits --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/45237395-fin-fun-mermaid-monofin-swim-fin-for-kids-swimming-flipper](https://www.desertcart.us/products/45237395-fin-fun-mermaid-monofin-swim-fin-for-kids-swimming-flipper) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-20*
