The pocket problem

One jersey pocket. Six things. And then it rains.

A phone, a couple of cards, a key, a spare tube, a multitool and something to eat — all of it loose in the same pocket. Everything rattles. The card ends up under the tube. And the moment the weather turns, the phone is the thing you're actually worried about.

How it's built

Mammoth Empire cycling wallet slid into the rear pocket of a cycling jersey

Anatomy

Built like it expects weather.

TPU-coated 600D polyester, so rain runs off instead of soaking through. High-frequency welded seams — no stitch holes, because a stitch hole is a leak. A YKK rain-resistant zipper, the part that fails first on cheap pouches. Six compartments plus an ID window.

Commute

Straight from the bike into a bag or a coat pocket.

04

Travel & EDC

Cards, cash and documents in one place that shrugs off rain.

Everything, in one pocket.

Phone up to 17.5 cm. Three or four cards. Folded cash. A house key. A spare inner tube, two tyre levers and a multitool. Plus an ID card, for riding alone.

Questions

Before you buy.

Will it fit an iPhone 16 Pro Max?

Yes. The phone compartment takes handsets up to 17.5 cm long. The iPhone 16 Pro Max is 16.3 cm, so it fits with room for a case.

Is it actually waterproof?

It's rain-resistant, not submersible. The TPU-coated shell and welded seams shrug off rain, road spray and sweat. Don't drop it in a river. In heavy rain, keep the zipper end facing down.

Does it fit in a jersey pocket?

That's what it was sized for — 20 × 10 × 3.3 cm and 100 g. It sits flat in a rear pocket without bouncing.
