Made of EVA material with water resistant design 

Just need a water bottle rack, great replacement for your saddle bag. A saddle bag needs to hold spare tubes and can be crammed in them, which is large enough for your cycling tools and obstructs your taillight, other frame bags that attach to the top tube have caused rub marks on your bike finish over times

The interior has pockets and netting to hold items in place while avoiding shake and abrasion

You can keep some emergency tools, glasses, house keys even car keys and other small items inside all the time

This zip capsule is convenient and can be easily set up on the water tank cage, fitting precisely in a water bottle holder without popping out when going over pumps

Product Size: 18 x 7.5cm
