Mono Cases Civilian Series Expander Pack Backpack (Black)

basically it has only one large zipperwhich I love, and the expanding function is very useful when it gets a little overloaded. The small zipper in front is great for pocket stuff when Im riding my bike around too. Great quality backpack, don't think I will be getting a new one any time soon.

Wanted a more mobile (thinner) pack to haul around a small computer and accesories with room for a sweatshirt or jacket etc. The trick is this back pack expands when room is needed in the main compartment and when extra space is not needed it hangs closer to your back. It also is constructed of durable materials and very water resistant.
