Review on 🚲 ROCKBROS Red Bike Saddle Bag - 3D Shell Design, Under Seat Cycling Seat Pack for Mountain Road Bicycles by Glen Elevyn

UPDATE 6/12/2022: The rubber seat tube band couldn't take the torture of the gravel I ride on (see photo). Luckily the driver behind me saw him fall down the road. All other original comments are still correct. Installed on my gravel bike. I have a spare hose, 2 CO2 cartridges, an inflator and a multi tool that probably has enough room in my wallet if I want to carry it around. It is very water repellent. I wipe it down after every ride and haven't seen any moisture in the bag so far.
