One object. Six decisions.
Engineered to disappear in a pocket and survive the water it lives in.
Built to seal
Sealed shell. Engineered to keep water out past board-leash depths.
Sand resistant
Grip flutes shed grit. No exposed hinges to clog around saltwater.
Built for surf
Designed in wet boardshorts, around the way pouches actually carry.
Pocket-friendly
Ø56 × 21.5 mm puck. Disappears into a coin pocket or clips to a boardshort key tab.
Threaded closure
Dual silicone O-rings. Single-start thread — engineered for static + dynamic sealing.
Disposal compartment
Fresh pouches up top, used pouches sealed below. Fresh in, used out.
One finish. One hundred units.
Field Issue 01 ships in Pōhōiki — deep onyx, the only finish on the first run.
Run with the Knukl Hedz.
The Knukl Hedz are our field-test crew — the people who actually use the gear. Drop your email and where you spend your sessions; we send pre-release units to a small pool before every issue ships.
"If you remember it's there, the carry has already failed."
Built like equipment.
Tolerances borrowed from cameras built for the same water. No extra parts. Nothing decorative.
"Designed to be the part of your kit you never think about."
Specs are engineering design targets for the case; independent validation is in progress. Every unit is wet-validated before it ships.
Compression seal
Engineered for static + dynamic sealing
Saltwater durability
UV-stabilised PP — salt- and UV-resistant, won't corrode
Drop
Engineered to a 1.8 m drop target
Field testing
Begins with Batch 01 — buyers are the field test
For people who stay out longer.
Not a movement. Not a lifestyle brand. A small group of people who ended up in the same parking lots.
"Disappears in the coin pocket. Comes out the other side of a six-foot set still dry. That's the whole story."
"I don't think about it anymore. Which is the highest compliment I can give a piece of gear."
"Built like a small camera. Treated like one too."
Quiet membership. Early gear. No newsletters.
No discount codes.
Built for the ocean.
Giving back through water.
KaheLock was made for people who live around water — surfers, beach days, boat days, and long sessions outside. For our launch drop, 10% of every purchase will be set aside to support Christian clean-water work.
After the launch drop closes, we’ll share the final donation amount and receipt so customers can see where the money went.
No nonprofit partnership, endorsement, or affiliation is implied unless stated otherwise.
Early access.
Join the first field test release. We'll send one email when units ship. That's the entire program.
Adults 21+ only.
