There are three of them, all made of the same sturdy fabric. However, the lining and details differ: there is one with green lining and details, one with pink and one with yellow. You choose.
The bags are 35cm wide, 32cm high and 15cm deep – perfect to hold A4 binders or groceries. They can be fastened to the bike rack securely thanks to velcro loops in the back.
