Tough bag, but with one major but easily fixed flaw. The bag is sealed at the top by folding down the top flaps against a protruding peg. The strap has a carabiner against one end that you then secure against the peg, and this keeps the bag from opening. If you head onto youtube you can see how this is done. The problem is that as soon as the carabiner takes any sort of weight (and considering how big this bag is, there's a lot of weight to be taken once it's loaded up), the bar slips and the carabiner opens, allowing everything in the bag to spill out. Thankfully I noticed before I checked it in as baggage, and used two zip ties as extra security. if you plan on really beating this bag around, definitely use something else to secure it shut. Anything like a little bit of cord to knot it shut, or a locking carabiner (with a screw down) would work great.
