Surf bikinis that stay on when the set rolls through

We design every piece to be worn in the surf, not just beside it. Here is what to look for in a surf bikini that stays where you put it.

Why bikinis go walkabout in the surf

A wave pulls you two ways at once. Thin ties come undone, straps close to the neck slide off your shoulder and skinny side seams roll the second you get dumped. What helps is structure: anchored straps, a band that takes the load and a snug fit.

The top

Straps that cross or meet at the back are harder to knock off than a neck tie. The Racer has crossback straps and an under-band, with medium support.

The bottom

For surfing and bodysurfing, swim shorts are much harder to yank sideways in a wipeout. A brief needs to fit snugly to stay put. Heads up: our Brazilian is a cheeky cut, so it has less coverage than a full brief.

Fabric matters as much as the cut

Go for a dense knit that feels firm when it's dry, since all swimwear relaxes a little in the water. Ours is recycled Italian nylon from Carvico — 80% recycled nylon with premium elastane, or 78% ECONYL® regenerated nylon with XTRA LIFE LYCRA® — a dense knit that stays opaque when wet and holds its shape through salt, sand and chlorine. Loose knits and cheap elastane go slack after a few sessions, and that's when things start slipping.

Shop the pieces

Everything's on presale right now, which is our way of keeping waste out of it — we only cut what's actually been ordered, so nothing ends up sitting in a warehouse or marked down into landfill. Estimated to ship early December. We'll email you if anything changes.
