I love this bag! I used it for a 14 day 6000 mile run this year and the straps held up beautifully. It has several different mounting options and lots of room for stuff (I was able to pack 8 days worth of undergarments, 2 pairs of jeans, 5 long sleeve shirts and a hoodie into the main compartment alone.). My only complaint is that the bag is only weather resistant. Water will still get to your clothes in a downpour if you do not deploy the supplied waterproof cover. The cover works great, but the inherent design flaw is one it was in the bag I had no way of securing my roll top bag to the top of it, unless I ran a long bungee from the luggage rack over the entire stack. I managed, but I didn't trust the securement. I'm sure there are ways around this that I have yet to try, but other than that this bag is a great investment.
