This thing is amazing. I have been fishing a simms hip pack for the past few months and wanted something a little bigger and waterproof. This was a natural choice. I LOVE it. It is super comfortable to wear and fits everything I need. I can throw big fly boxes in there and a sandwich for the day and still have room. Its my go to hip pack for long days on the water. The only down side is the zipper is fairly hard to close and you have to make sure it closes all the way or water will get in. It also doesn't have much internal pocketing or organization which can be kinda frustrating. Everything that goes into the pack goes into one big pocket which can make it hard to find smaller things in a hurry. Overall, I love this thing to death.
