My to-go-to surf suit

I own both the black and the white version of this gorgeous suit: It’s the best and most comfy for surfing! Fits like a glove, with a handy front zipper (way better than a back zip if you ask me!) and super light weight and functional material! Love!!!

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.
