"Get the water-sealed one. One of the first 100."
Water

Sealed by design.

A single silicone O-ring seal — the same idea as a dive housing — keeps rain, splash, and spray out, and it floats if you lose it off the board.

The case is engineered to IP68 design target (sealed fresh chamber, 1 bar / 33 ft), wet-tested in development.

The object

Six decisions, no decoration.

Sealed

Single silicone O-ring. Engineered toward an IP68 design target.

Floats

Sealed & dry, it waits at the surface instead of sinking.

Octagon grip

Find it by feel. Open it one-handed — cold, wet, or gloved.

Fresh in, used out

Holds 5–7 fresh pouches; a divider walls off a sealed disposal side. Spent never touches fresh.

Threaded

Single-start threaded cap — one turn to seal. Disposal is an internal compartment, not a separate port.

ASA · UV & saltwater durable

UV-stable 3D-printed ASA, designed on Oʻahu.

03 / Access

One turn. Open.

A single-start thread — off in about a turn, on in about a turn. Sized for wet hands, cold hands, one hand still on the rail.

Single-start · M45 × 3 · Radial silicone O-ring

KaheLock octagonal case with the cap lifted off, showing the sealed neck and the divided chamber.
Inside

Two chambers. Fresh in, used out.

One body, split down the middle — fresh pouches on one side, a sealed disposal side on the other. Nothing loose, nothing wet, nothing you have to think about again.

Five-to-seven fresh · Sealed disposal

Inside the KaheLock body — a divider splits it into a fresh side and a sealed disposal side.

DesignedOʻahu, Hawaii

On the 3D-printed ASA: no water gets in directly — the O-ring seal holds. Over a single 3–4 hour session in the water the body can take on a little moisture. The production run will be injection-moulded; every founder gets one for the price of shipping, with a lifetime warranty.

Honesty

Why purchase?

The case is 3D-printed in ASA and engineered toward IP68 — a water-sealed carry case. We build in small runs of 100 and hand-check every one, so the first batch is genuinely limited — and you're getting one of the first.

You purchase yours at the founder price, and every unit is wet-tested in development.

The first run is a small one. You're one of the first 100.

Mark

Kahe. To flow.

The wave pressed into every lid is the word the case is named for — kahe, Hawaiian for "to flow." Under it, the coordinates where it gets tested.

Founders · Batch 01

Be a founder.

Field Issue 01 isn't just a case. Purchasing Batch 01 puts you at the front of every issue that comes after — and gives you a small set of quiet privileges along the way.

01

Lifetime early access

Every future field issue lands in your inbox first — before public release, before any press.

02

Custom-scanned helmets

Field Issue 02 — big wave helmets fitted to your skull. Founders scan first.

03

Hardshell board travel

Field Issue 03 — surfboard travel cases. First dibs go to founders, at founder pricing.

04

Beta tester pool

Founders are in the pool. Before every issue ships, we send pre-release units to a small group — real water, real conditions. Your notes shape what we make next.

Founding 100 get the Club — free, for life.

The four perks above are the Club: early access and founder pricing on every Field Issue we ever make. Free for Batch 01 buyers, for life. After this run, membership is paid — and you'll never pay it.

Future field issues (02, 03, and beyond) are planned, not promised. Founder benefits tied to future products apply if and when those products are made.

Every founder purchases the water-sealed case — the 3D-printed in ASA, IP68 version — at the founder price, and keeps founder pricing on every future issue.

Founder status is tied to Batch 01 orders and persists across future issues. Your order is fully refundable until it ships.
