Great saddlebag
"This saddlebag from Pro performance is really well designed. Simple Velcro straps firmly attach to the saddle and seat tube with minimal fuss. The zip at the back also allows access to the contents without taking the bag off the bike. It’s also properly waterproof and I’ve had no problems with water ingress despite riding in the wet constantly (it’s the UK) since it was purchased! The shape and fit also means it is relatively aero efficient. The medium size isn’t huge but there is plenty of space for TPU tubes, tire levers and a multi-tool. The convenient pocket at the back will also hold quick-links, tire patches and shifter batteries. Finally a light attachment on the outside works well with a range of small rear lights."
