I bought this bag for your daily commute by bicycle. The bag can hold everything I need: smart, Purse, House Keychain, corporate identity and corporate key. In spite of this stuff is still some air in the bag. Thus, the Micro offers 100 exactly the optimal size for my project. Do not Globig also acts on the bicycle and makes in terms of processing a great figure. I have the bag for 3 weeks now in use and can you recommend everyone who did not want to run empty mitsich his backpack.
