This bag is well constructed.  I was both surprised and pleased with the many compartments with zippers and Velcro to make it easy to organize.  The size of the bag is medium size but it is very light weight.  It can hold a lot of items.  Love the Velcro compartment in the front for quick easy access for keys.  I have several other small Kavu bags and have washed them and they do not losing their shape.
