The planet's finest wetsuit.

One design. One thousand units. Yamamoto limestone neoprene, graphene-lined, made-to-measure in Portugal. When the thousandth ships, the line ends. There is no v2.

“Strive for perfection in everything you do. Take the best that exists and make it better. When it does not exist, design it.”

Sir Frederick Henry Royce

A closed ecosystem, members only, by design.

Founded in 2018 on a single principle: build one wetsuit, at the highest standard the planet can produce, for the smallest number of surfers who understand why that matters. We do not chase O'Neill, Rip Curl or Quiksilver on volume, and we never will.

Members receive a single object: the Aptus 1.0, plus the dispatches, live experiences and repair-first ownership that surround it. Nothing is sold at retail. Nothing ever will be.

Everything worth knowing about the Aptus 1.0.

Materials. Engineering. Every question we've been asked, answered in one place.

01 · Material

Yamamoto #39. Kyoto, since 1964.

Nitrogen-infused closed-cell limestone rubber. A honeycomb interior traps warm air against the body. Cell-wall density keeps the water outside, not inside.

Cell typeClosed, N₂-infused
StructureHoneycomb interior
Stretch480 %
AbsorptionUnder 1 % uptake

02 · Construction

Glued, blindstitched, taped.

Internal liquid tape at every join. No paneling where paneling is not needed. Cut and assembled by hand in Ericeira.

03 · Technology

A graphene thermal core.

Conducts body heat evenly rather than trapping it in pockets. Dries fast. Stays quiet through the paddle.

05 · Answered

Asked before a serial is claimed.

Why limestone neoprene?

Denser cell wall, lower water absorption, no petrochemical base. Lighter wet, warmer longer.

How do I take my measurements?

We send a guided 18-point kit once your serial is reserved.

Is the deposit refundable?

€195 comes off the €799 total. Refundable in full until your suit enters cutting.

Will there be a v2?

Not of this. When the thousandth unit ships, Round I closes permanently.
