Perfect Fit & Great for Water Activities

The Mentawai is my favorite fit! It's sexy and I'm sure everything stays in place when I'm in the water.

Charlene Dickson
Highly recommend!

I have used my suit freediving and hanging with my kids on the beach. It is fully functional for anything water related. I did size up - normally a medium in the US but size large fits perfect. It is good quality - I can see myself using this suit for years.

Jenna Tanner
Love that it's sustainable!

Love this suit! It stays in place while I’m freediving and is super flattering. Love that it’s made from sustainable materials as well!
