I am on my second Revolution bag. My first bag was in good enough shape to sell. I have been using the dual pack for over a year, and I havn't seen any wear yet. I like the dual pack because I can pack my umbrella, stool, lunch, extra water, and all the discs I need without any problems. The best feature is the waist and chest straps to take the weight off of your shoulders. also, the shoulder straps will not hit the dirt when you set your bag down, keeping your shirt clean. This bag is the bag of all bags, hands down.
