    The Mentawai - Midnight

    I wore my one piece to the ocean yesterday and it was amazing! What I loved about it was the Econyl because it really holds everything in so well!
    I have posted pictures on my instagam @not.nat.geo and @reck.lessabandon1810 as I had a butterfly freediving day in the ocean and wore it with my wings. A great combo for a wonderful dive. Thanks Ocean soul it was a great product.

    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!!!

    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.

    FAQS

    We line all our snow white surf suits with a beige econyl sustainable fabric, to prevent them from becoming transparent.

    Our one piece surf suits do not have built in support. They are double lined and are a firm cut, designed to hold you in. We have customers from a AA-D that are happy with the support with our surf suits.

    You can adjust the fit of each surf suit by hitching the leg high up on your hip, which gives you brief coverage. Or pull it down on your hip for more coverage.

    If UPF protection is important to you, opt for the darker colours. The Sulawesi in Midnight provides the most UPF block out, due to the dark colour of the fabric and long sleeves.

    All our one piece surf suits are designed to be like shape wear and hold you in. If you prefer a more relaxed feel, size up and if buying the midnight go up two sizes, as the black colour doesn't have as much stretch due to the dying process.
