“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

Preorders · Open

Preorders are open for the current allocation.

We believe the ocean demands fewer, better things.

The Aptus 1.0 is the culmination of several years of rigorous development, designed to bridge the gap between thermal efficiency and unrestricted movement. We erased the industry-standard compromises between warmth and weight, craftsmanship and scale. This is not off-the-rack; it is a precision instrument built for your exact physiology using the best materials possible.

We are not chasing O’Neill, Rip Curl, or Billabong on volume and we never will. One product. One 1,000-unit global allocation. Built to be the best wetsuit on the planet, not the most wetsuits on the planet.

When you reserve an Aptus 1.0, you receive a single, individually serialised object, backed by direct dispatches and dedicated support. Distributed exclusively through our factory.

Aptus 1.0, front
Andrew “Cotty” Cotton

Founding athlete

I’ve surfed some of the biggest waves on the planet and worn some of the best equipment ever made. Born Slippy is the wetsuit I choose to wear now. The custom fit is incredible, the CORECELL technology is next level, and the Yamamoto neoprene feels like cashmere against your skin. It’s performance without compromise.

The anatomy of the Aptus 1.0.

Uncompromising materials, radical engineering, and absolute fit.

Yamamoto branded neoprene, close
Yamamoto Limestone Neoprene.
  • Pinnacle of wetsuit performance, premium Japanese #40 and #39 closed cell nitrogen Limestone Neoprene.
  • Absorbs less than 2% water weight, making your suit lighter in the wave and noticeably faster drying between sessions.
  • Structural integrity that retains its shape, warmth, and elasticity over multi season wear without thinning or stiffening.
Blindstitched seam, close
GBS triple-taped seams.
  • GBS, glued and blindstitched, with triple-taped seams for maximum warmth, flexibility and durability.
  • Creates a completely impermeable barrier that blocks ice cold water ingress at every stitch line.
  • Total warmth retention and seam flexibility that eliminates paddle restriction and prevents seam tearing under heavy wipeouts.
Thermal lining matrix, close
CORECELL thermal technology.
  • Micro-Chamber Matrix. Proprietary internal chambers trap insulating air against the body, creating a highly efficient thermal barrier.
  • Zero Water Absorption. Closed-cell construction absorbs no water, keeping the suit lighter, faster-drying and less prone to retaining sand and dirt.
  • Maximum Thermal Efficiency. Engineered as an alternative to conventional fleece and graphene thermal linings, maintaining a warm insulating layer directly against the skin.
Surfer floating, suit under load
29 Point Anatomical Profile.
  • Tailored pattern cut specifically to your unique body dimensions and muscle contours.
  • Eliminates dead air space, underarm pulling, and lower back rubber bunching.
  • Absolute elimination of cold water flushing, giving you a custom second skin feeling in peak surf conditions.
Neoprene flexed through a full curl
180° Shoulder Articulation.
  • Seamless upper torso pattern cut to match the full rotational arc of your paddling stroke.
  • Designed to minimise rubber pull through the full range of motion, along with chest compression and shoulder fatigue on long paddle outs.
  • Zero resistance at maximum extension, allowing you to stay in the water longer with uncompromised paddling power.
Surfer on the shoreline
Capped Production Engine.
  • Capped at 1,000 total units worldwide, released across four quarterly allocations of 250 units. When unit 1,000 ships, the Aptus 1.0 line ends.
  • Guarantees total quality control, zero factory rush jobs, and zero commercial overproduction.
  • You own a rare, bespoke piece of high performance equipment rather than a mass market commodity.
