Took this bag with me for field training. It rolled over dirt, through mud and through grass. I was able to pack a great deal of stuff into the bags (used 2) and the compartments were useful for storing little things that I wanted to get to quickly. The bags did get soaked once and the items in the side pocket got wet, but nothing got wet in the large compartment. Bag got the job done and hopeful that they last a few more years.
