I have an Older Model Gateway BackPack bag.
IT has held up for over 2 years and the only things that are Wearing out is my Right SHoulder strap(I use it th emost) and MY divider pipes are starting to come out of the Dividers.
IT has served me well, but I would NOT recommend this backpack Bag. It will hold up, but IT is Quite Uncomfortable to wear and DOesn't seem to ever sit right on the back.
YOu are better off getting a Tour bag from a company and adding Quadshocks.
I'd highly recommend a REvolution bag with QuadShocks.. Recommended by many top pros and Just a great back to throw altogether. I think they might also have a warranty.
I have a newer Gateway Backpack bag and it had plenty of zippered compartments and I find it very comfortable. I haven't tried all the bags out there but as it is right now (I've been using the Gateway bag since the beginning of the year) I have no reason to try anything else.
I chose the Gateway Bag over the Revolution bags because of cost, capacity and disc access. Pretty much all I had to go on was pictures, lists of features and online reviews. I thought the backpack bag looked like it was easier to access the discs and the listed capacity was larger. It was also cheaper (especally when you factor in a dual strap) and praised just as much in intelligent reviews ("Only ever buy REVOLUTION, it's the RULZEORS!!!!" doesn't count).
I don't doubt you'd be happy with either the Gateway or Revolution bags if you want to spend the cash.
