Review on 🚲 Waterproof Lixada Bike Rack Bag - Cycling Rear Seat Pack for Road and MTB Bikes with Cargo Storage - Bike Trunk Carrier Pannier Handbag by Jeremy Floyd

I am very happy with this bag. It holds its shape very well due to the hard sides and is larger than any other backpack I've used. I can't guarantee how waterproof it actually is, but the zips are very similar to those on my very expensive raincoat. It came with a rain cover which I will never use. I don't think you will be disappointed if you buy this bag. Two velcro straps at the bottom and one at the front keep the bag securely in place without shifting it on the rack.
