I bought this pack for the 3day, 60 mile walk for breast cancer. I have been training with it for two weeks. It's has pleanty of pockets and room for all the essentials that I need. There is extra padding bult in that makes it much more comfortable than your run-of-the-mill pack. The only thing I don't like about the pack is the water bottles, they arn't big enough for my hydration needs. So I'm using other water bottles insted, and they fit in the holders wonderfully!
