Review on 🏍️ Black-Skull Motorcycle Tool Bag - Universal PU Leather Fork Bag Saddlebags Handlebar Bag Sissy Bar Storage Tool Bag for Honda Kawasaki Suzuki Yamaha Sportster by Gary Reed

So the side flaps will bulge and I don't think you want to rely on waterproofing (the material can be waterproof but the design allows if the flaps pop out and release water in.) You can make it more waterproof by pinching the sides after closing, but that's a bit silly. Overall, for the price, you really can't complain. I don't think you could even come close to getting anything at this price for this design (which matches my existing bags).
