Rhinowalk Bicycle 3 in 1 Pannier Bag 65L Large Capacity Waterproof Multifunctional Bicycle Panniers Side Bag Cycling Storage Bag Rucksack Shoulder Bag Bicycle Accessories for Mountain Road Touring Bike

The material is of good quality and worth the price, very usable. It has plenty of capacity and doesn't take long to wait. I haven't used it yet, but overall it's good. It can be installed with a standard rear rack, but the hooks provided can only hang and can't lock, which is a bit disappointing. It would be perfect with just a little improvement.
