Love my M.U.L.E.
I gave this pack 4 stars because I wish the main pocket was just a little bigger. But, I have used this pack a lot and it is a great day trip bag. Over last summer I worked for a conservation corps and I used this pack for my chain saw bag. The MULE held my saw accessories,3L of water, a small first aid, a small lunch and some snacks. This bag is tough and I highly reccomend it!
