Roll-top lunch bags are the best for bike commuters

Roll-top lunch bags are the most secure lunch box for a bicycle commuter because the closure can’t pop open and it’s waterproof.

Zippers fail. Latches work loose from road vibration. Velcro gives up. A roll-top bag doesn’t have any of those failure points. You fold the top over two or three times and buckle it down. It stays closed until you open it. The only way it’s coming undone is if the buckle itself breaks, and those are simple, tough pieces of plastic.

The roll-top design is also waterproof. If you get caught in a downpour, your food stays dry. Same goes for leaking containers inside — nothing drips onto your laptop or clothes. And because it’s soft-sided, it squishes into a backpack or pannier more easily than a rigid box.

If you’re worried about crushed food, put a hard-sided container inside the roll-top bag. That gives you both crush protection and a guarantee your lunch isn’t scattered across the bottom of your bag. Brands like Sea to Summit and Outdoor Research make solid options, but any dry-bag style lunch carrier works.

Your back and your lunch will both show up ready for the afternoon.
