ROCKBROS Waterproof Mini Saddle Bag — 0.4L
⭐ Club Tested
Got caught in a proper downpour with one of these under the saddle and everything inside stayed bone dry — the rainproof coating actually does its job.

🌧️ Rainproof Build
A rainproof polyester exterior keeps a tube, tool, and a couple of CO2 cartridges dry through wet rides.

Compact 0.4L sizing means it tucks under the saddle without rubbing your thighs or catching on your shorts.

💬 From the Supplier's AliExpress Listing
4.7★ · 227 ratings from AliExpress buyers of this item — shown here for reference on real-world fit and quality, not from Kakepuku Bike Club's own customers.
"Smaller than I expected but aesthetically great and the grips are very very strong. Nothing moves at all. It has capacity for a normal 700cc camera, two dismounters, a few Allen keys, and two CO2 cylinders." — AliExpress buyer
"This bag is very small and compact at 0.35l. It's just the right size to put in a spare tpu tube, co2 regulator, 16g co2 cartridge, tire lever, and a contact lens case with dish soap (for reseating the tire). I'm very satisfied." — AliExpress buyer
Small enough to forget it's there, useful enough to be glad it is.
