Lavender Nunui (teen/adult size) Mermaid Monofin

Regular price $49.95

Did you know? Nunui means "big" in Hawaiian, perfect for our larger monofin! It's pronounced Ni-new-ee.

The Nunui monofins are for use with our JS, JM, and JL size tails.

Our patented mermaid monofin (swim flipper) is the best monofin available (US Patents 9561401 and 9925416). Not only does it help you swim like a real mermaid, it keeps feet from sliding around, is so comfortable to wear, and won't break.

Unlike other monofins, our swim fins do not require any babying. You can bounce on the tips, push off pool walls, even hop around in them without any fear of the fin breaking -- though you can break so please be careful.

Lasts years

We have had 3 monofins and they have all lasted about 3 years, but our 1 (and last) from FinFun was broken in less than a month.

Great Beginner Fin

I bought myself this fin last spring and I've been pleasantly surprised by both the company and the product.OK so first off, within a month of use a large crack appeared up the middle ridge. I contacted Suntail and they immediately sent me a replacement. I haven't heard of this happening to other people, so I assume mine was just a dud. Since then, the only negative thing that has happened so far is a little stretching in the neoprene cover, which is to be expected when a fin is used often. On the bright side, the fin's design and all the colors are stunning. Would buy again.

Superior Product

We purchased a fin and tail from another company about 3 years ago. The fin was somewhat fragile and the foot holes were uncomfortable. This was very disappointing since we paid over $200 for the product! When this company started I was VERY interested to say the least, however it took a year or so for it to get off the ground and begin producing the teen/adult size fins. I can't say enough about the quality and comfort of this product! It's durable and easy to care for. It fits my daughter's size 7 feet and my size 10 with no problem. The foot pocket can be completely removed for easy care and cleaning. We are beyond satisfied and would absolutely recommend this company and their products.
