blooper back packs bike front organizer I'm selling this because the size was different from what I expected. Referencing the following from Instagram: It has two compartments: the main compartment and a mesh pocket on the front. It's designed to be used in conjunction with a dry bag, etc., and is intended to be attached to a rack. You attach the included bungee cord to the rack, and then attach the organizer to the rack using the four hooks on the back of the organizer. (The last photo is a prototype, so the attachment method is different.) A key hook is included in the mesh pocket. The main compartment has more capacity than it looks.
