Castelli Undersaddle Mini saddle bag

It's really a small bag: you can fit an inner tube (butyl), a multi-tool, tire levers, and at this point, there is not much space left (for my part, I add a usb-c cable for possible charging of a phone). But it's perfect for my use! There is indeed a small net that delineates a small storage space separate from the rest (I put the usb-c cable there). Impeccable waterproofing, nice pouch, the zip is easy to manipulate, I am very satisfied with this investment. (Translated review)

Small but big enough for the repair kit. Top notch! (Translated review)

just enough to put the essentials (minutes / 1 inner tube / 1 Co2 cartridge) (Translated review)

Compact (Translated review)

Superb finishes as often with Castelli. Ideal size for a bedroom, co2, multi tool and patches. Easy storage because it's well rectangular. Used in light rain and the inside stayed dry. (Translated review)

Perfect for storing disassembled multi-tool tire from Synchros very fine Impact + CO2 cartridge inner tube (Translated review)

Superb bag well finished and very practical for storing a spare tube, tire levers, and a multi-tool. (Translated review)

Very small but allows you to fit three dismounted tires and a tube, perfectly waterproof under the saddle. (Translated review)

This bag, even if it doesn't seem like it, is perfect for a long ride. Despite my doubts, I manage to store a tube, 3 tire levers, a cartridge and the tool that goes with it, a set of flat tools (see the brand Synchros). Very good purchase, and super price! (Translated review)

Bag presented as "mini". I put a tire lever + inner tube in it, but it is too big. I had to put a cloth to be able to tighten it. (Translated review)
