84% Repreve Polyester / 16% Spandex

Increased compression and structure. Smooth, supportive feel with improved shape retention and higher resistance to pilling. Designed for high-impact training and heavy wear applications where durability and performance are essential.

Flatlock Seams

Stitched to eliminate chafing during extended sessions.

8-Way Stretch

Moves in every direction for unrestricted performance.

Chlorine + Sweat Resistant

Maintains colour and integrity wash after wash.

drop

Machine Wash Cold

Wash on a cold, delicate cycle. Warm water damages elastic fibres and shortens garment life.

prohibit

No Tumble Dry

Air dry only. Lay flat or hang to dry away from direct sunlight to preserve shape and colour.

Wash Separately

Wash dark and light pieces separately for the first few washes to prevent colour transfer.

No Fabric Softener

Avoid fabric softeners and bleach — they break down moisture-wicking fibres and reduce performance.

Designed for long-term durability using intentional materials and responsible production practices where possible.

Our model is 174cm and wears a size S. True to size — we recommend sizing up if you are between sizes or prefer a less compressive fit.

OUR COMMITMENT

BETTER GEAR. Less waste.

Every piece we make is a commitment — to keeping waste out of our oceans, to building products that outlast fast fashion, and to being transparent about how we get there. We don’t believe in gear that falls apart after a season. We build for performance that lasts, because the best thing for the ocean is something you never have to replace.

Sustainable Sourcing

Where possible, we choose recycled and lower-impact fabrics — like Repreve polyester made from post-consumer waste. We're expanding this across more of our range.

timer

Longer-Lasting Designs

We engineer our pieces for durability — fewer replacements means less waste. Quality construction that holds up session after session, so you buy less over time.

Conscious Packaging

We've reduced plastic in our shipping materials and moved toward recyclable mailers. It's a small step, but every improvement counts on the journey to better.
