Locked in two seconds. Opened only by you.
Clip both zips in, spin a dial, done. No key to carry, no padlock to fumble with on a moving train.
Get yours now 👉That's all it takes to open an ordinary bag.
A packed train. A busy square. Your eyes on your phone or the map. A zip behind you slides open and you don't feel a thing.
- A backpack sits behind you, out of sight, all day.
- Zips open silently, and in a crowd nobody notices a hand.
- Abroad, losing a passport or cards can end the trip.
Ordinary bag
Locked sling
Drag to compare. Same three seconds. Nothing taken.
You're the pickpocket. You have three seconds.
The lock is set to a random code. Tap the dials and try to open it before the timer runs out.
Tap any dial to start the clock.
Both zips lock in. One code opens them.
Most "anti-theft" bags hide their zips and hope. This one locks them. The two main zip pullers clip into a combination lock on the side, so the compartment stays shut until you dial your code.

Set your code
It ships at 000. Set your own three digits in under a minute.
Clip both zips in
Pull the zips together and click both pullers into the lock.
Spin to lock
Turn a dial and it's shut. No key to lose, no fiddly padlock.
Go on. Try to open it.
Drag the zip puller away from the lock. On most phones you'll feel it too.
Everything you carry. Locked.
Slim on the outside, organised inside, and made from fabric that takes the knocks.


Tougher than it looks+
A dense, water-resistant fabric that keeps its shape and shrugs off everyday knocks.
Made for daily commutes, packed trains and the odd drop on a station floor.

Passport pocket, against your back+
A hidden zip pocket on the back panel. It sits flat against your body, where hands can't reach.
Big enough for a passport, boarding pass and spare cash.

Slim outside. Your whole day inside.+
Fits a 9.7" tablet, phone, wallet, passport, power bank, keys and sunglasses.
Internal pockets keep small things organised instead of sinking to the bottom.

Your phone charges while you walk+
Plug a power bank in inside, plug your phone in outside. No hunting for sockets.
Works with any standard USB power bank.

Rain-ready+
Water-resistant fabric keeps light rain and spills off your things.
Wipe it clean with a damp cloth. Let it air dry.

Card slot in the strap+
A slim slot built into the strap. Reach your card without ever opening the bag.
Your card rides on your shoulder, in front of you, not loose in a pocket.
Pack it and see.
Tap what you'd normally carry. Slim on the outside, room for your whole day inside.
Your bag is empty. Start packing.
Illustration only. Fits a tablet up to 9.7".
For people who'd rather watch the city than their bag.
Headphones in on a packed train. No hand on your zip, no checking every stop. Just your commute, back to normal.

Before you buy.
How do I set the code?
The lock ships set to 000. Press and hold the slider on the lock, dial your new three digits, then release. Full instructions are on the card in the box.
Is a power bank included?
No, a powerbank is not included. The sling on its own has a built-in USB port and internal cable. You plug in your own power bank inside and your phone outside.
Will it fit a laptop?
No. It fits a tablet up to 9.7", plus your phone, wallet, passport, power bank, keys and sunglasses. It's designed to stay slim and close to your body.
Is it waterproof?
It's water-resistant. The fabric keeps off light rain and splashes. Don't submerge it.
Can I take it on a plane?
Yes. It's small enough to go under the seat as a personal item on most airlines. Check your airline's limits before you fly.
Which shoulder does it go on?
Either. The strap adjusts and switches sides, and you can wear it across your chest or on your back.
What if it's not for me?
Send it back within 30 days for a full refund. No forms to argue with.
Not a backpack. A safe you wear.
Take it on your commute or your next trip. If it doesn't earn its place, send it back within 30 days for a full refund.
