The three-second problem
3s

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.

Drag to compare. Same three seconds. Nothing taken.

Try it yourself

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.

How it works

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.

Questions

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.

30-day money-back guarantee

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.
