Mentawai one piece swimsuit

Love this swimsuit it’s a very flattering design so looks amazing on, and I love that my back also has great coverage from the sun. I always get comments when I wear this.

C. (Sosua, Cabarete, DO)
So elegant and functional

I love this suit! Not only is it great for surfing and freediving, but it also looks so elegant and classy on. Everyone always comments that I’m ready for a Bond movie in it! Flattering, functional and comfortable.

Perfect swimsuit!

I finally purchased the nautical mentawai swimsuit and I am so very glad I did! This swimsuit made well and fits perfectly! It is so flattering and also functional so you can surf, paddleboard and have fun knowing your bathing suit is secured and won't ride up or fall off while being active in the water. My next purchase will be the sulawesi long sleeve in midnight, love the long sleeves for added sun protection. Overall I recommend this swimsuit and am very grateful for the beautiful design of my new mentawai swimsuit!

Highly recommended!

The best swimsuit I have,and I have more than 50….)
The quality of the fabric is the best.
The only thing that I was upset about is the size.
I ordered size Medium and it was lose size Small.
I had to sent it back to you,which was a hassle and had to wait for Another one.

But-it is one of my best swimsuit as I am paddling on SUP on a regular basis.
Thank you,
