+1 To what Alan said, and for better or worse to what TripleT had to offer. Endo not so bad-o with my Mule. I thought the thing was gonna be too big as well, but comes in real handy, especially out at Boyette where you do not come back and visit your car or truck during the ride. Absolutely get one with a 3 liter bladder no matter what, especially right now as it is Africa hot. I'm a pretty small guy and the Mule does not feel big at all. Other than my bike, best purchase I have made since becoming addicted to this sport.
