Customer feedback

Comments: I bought the Nathan X-Treme 3.0L Pak about three months ago for training on 3 marathons scheduled in Septemnber, October and November 2010. As I was training in the mountains for my long run I needed that much water for my three to four hours long run every Sunday. My back shoulders were getting bruised from the straps and he bladder leaked. With no other pack, I had to take Nathan with me on my high altitude marathons. 3 miles into the first marathon race I had to remove Nathan and leave it at the water station as my shoulders were bleeding so bad.
