GRAVEX 15

I’ve taken this bag on a few grocery runs in heavy rain, and everything inside stayed completely dry thanks to that waterproof fabric. It’s also surprisingly easy to snap on and off the bike rack, even with gloves on.

This fabric feels tougher than any other bag I've owned, and it handled a sudden downpour without a single drop inside. It's also really handy that it clips on and off the bike so fast when I stop for groceries.

I was a bit skeptical about how waterproof a bike bag could be, but after riding through a downpour with groceries inside, everything stayed perfectly dry. The 420D recycled fabric really lives up to the "super rugged" claim, and the quick-release mounting makes it easy to take on and off.
