They aren't kidding when they say this is a big bag. I took it on a long trip with 2 sets of clubs in carry bags and had no problem fitting them in as well as extra items. It is built sturdy and has withstood 3 cross- country trips so far with no major signs of wear or abuse. There are pockets on the inside and outside and inner straps to help hold your bag in place. Most airlines will allow you 70 lbs with a golf bag. Great product. I would recommend this to anyone that is taking thier clubs on an airline or just has a lot of stuff to carry. I recommend going to the hardware store and getting a piece of 2" PVC cut a couple inches longer than your longest club to avoid damage if the bag gets dropped on it's head. This can be a problem with any travel bag. I shopped around a while before deciding on this bag and couldn't be happier!
