Why we use

Limestone Neoprene

Neoprene is neoprene, right?

Not quite. Most neoprene swim kit starts with petroleum. Ours starts with limestone.

We use high-quality limestone-based neoprene across our socks, gloves and body warmers because we wanted a material that performs brilliantly in cold water, lasts season after season and is a more considered choice for the planet.

Four reasons we choose limestone

  • LOWER IMPACT

    Made using calcium carbonate from limestone rather than petroleum as the primary raw material.

  • WARMER

    Tiny air pockets within the material help trap heat, keeping you comfortable in cold water.

  • MORE FLEXIBLE

    A flexible construction that moves naturally with you without feeling stiff or restrictive.

  • BUILT TO LAST

    Durable and resistant to UV and ozone exposure, helping your kit keep its shape season after season.

SO, WHAT ACTUALLY MAKES IT DIFFERENT?

Traditional neoprene is commonly made using petroleum-based materials. We chose a different route.

Our limestone neoprene uses calcium carbonate as its primary raw material. Limestone is an abundant natural mineral, rather than a finite fossil resource, and can be sourced for the long term.

The result is a high-performance neoprene that does what you need it to do in cold water, while helping us move away from relying solely on petroleum-based materials.

Better in the water. A more considered choice for the planet.

Here's the science

01 / A MORE CONSIDERED CHOICE

Less petroleum, more limestone

Petroleum is finite. Limestone is abundant and can be sourced for the long term. Our neoprene uses calcium carbonate from limestone rather than petroleum, with processing increasingly powered by renewable energy. For us, it’s about making more considered choices at every stage. One material choice can make a difference.
02 / MADE FOR COLD WATER

Warmth without more bulk

Cold water is tough enough. Limestone neoprene has a closed-cell structure filled with tiny air pockets that help trap heat, providing excellent insulation without extra bulk. That means warmer, more comfortable kit that still lets you move naturally. More warmth. Less bulk. More time enjoying the water.
03 / MADE TO GO THE DISTANCE

Good kit shouldn't be disposable

We believe the most sustainable product is one you don't need to replace too often. Limestone neoprene is highly resistant to UV and ozone exposure, helping it resist cracking and brittleness while keeping its shape season after season. More swims. Fewer replacements.
04 / MADE TO MOVE

Flexible where it matters

Nobody wants swim kit that feels like cardboard. Our low-density limestone neoprene stretches and moves with you, making socks, gloves and body warmers comfortable rather than restrictive. And when you're standing on a chilly beach, that flexibility makes getting changed easier too. Flexible, comfortable and ready to move with you.
05 / KINDER TO YOUR SKIN

Comfortable in every sense

Limestone neoprene performs well without relying as heavily on some of the additives used in other rubber materials. Fewer additives can mean less potential for skin irritation, making it another reason we chose a high-quality material from the start. Better performance. Thoughtful materials.

Better materials,

Better Swims

We don't think you should have to choose between performance and making more considered choices.

That's why we've chosen limestone neoprene for the products that get you through the coldest part of your swim. It's warmer. It's flexible. It's built to last.

And it's one more way we're trying to make better kit for the women who refuse to watch from the shore...

...one cold dip at a time.
