In trying to keep the pack light, but carry some larger lenses (Canon 100-400L, Sigma 18-35) along with standards, there are times a ultra wide just won't fit. I am using this for the Tokina 11-16 which I like to bring when heading down tot he beach, but use to have to choose between the 100-400 or it when only wanting to use the ChangeUp system. This solves that as I can attach it to the belt portion and off I go. Perfect size and has all the standard benefits of TTP stuff - padding, rain cover and easy to attach/detach to their systems.
