Bought this bag because my mate had one and he said they were really good. Packed my kit in it and headed off to Iraq. When I got there, all my kit was still in it and the Zips all worked fine. So hopefully when heading back to the UK in a few weeks time and I have to open my bag a dozen times before I even get on the plane, the zip wont break like it did on my old suitcase and I wont have to worry about my pants and socks whizzing around the conveyor belt in London Heathrow. Good quality material, well made, worth the money!!!!!
