The full brief bikini bottoms are my go to for my daily cold water dips (I mix and match the tops). I love the benefits of cold water therapy and the full brief provides that extra comfort and warmth.

I love my cheeky bikini bottoms for underwater diving shoots and also wearing in warm waters. I choose to wear these when I am on my stand up paddle board so that I get an extra tan.

These are the perfect shorts for wearing in the surf because they stay on but are still cute and stylish. I particularly love the back pocket with the hidden key loop and rare zip.

Sarah N, Australia

Designing our bikini bottoms was very intentional because of the different water experiences they would be used for. Firstly, they have to stay on in the waves. Secondly, we needed to have different coverage options with styles designed to suit every body. The sports-luxe retro leg lines are a nod towards my favourite pair of stubby shorts that I used to wear in the surf in my younger years. They were second hand, they were comfortable, and the stayed on when I was cliff jumping into the sea or surfing in warmer waters. These plant-based, active bikini bottoms are perfect if you're in the sea more than you're on the beach.

Sustainable Bikini Bottoms FAQs

Where can you ship my bikini bottoms to?

We will ship to anywhere in the world. Read our shipping terms here.

What body types the bikini bottoms work for?

The Clean Lines collection was designed to cater to all body types, celebrating the female form in all shapes.

The full brief bikini bottoms are our most popular as they offer the traditional medium-full coverage of a brief, finished with a retro-shorty leg line. Pull higher up the waist  if you want to achieve a cheekier, high-waist look.

The cheeky bikini bottoms offer a cheeky-cut at the back if you’re looking to tan your buns in the water or for a more feminine look for those underwater diving shots.

The high waisted surf shorts are the perfect sporty bikini bottoms that provide more coverage and support. They have an elastic waist band and zip fastening at the back, sculpting the body in all the right places.

Here is our size guide:

What is the best way to care for my bikini bottoms?

Be sure to rinse your Yulex bikini bottoms in freshwater after use and hang to dry in the shade. Pay special attention to rinsing the zip if you have been in salt water. Be careful of sharp objects such as rocks and jewellery when putting on or taking off the bikini bottom. Read more in our wear and care guide.
