This duffel is everything you want. I just completed a rough weather, rough terrain, 5700 mile 21 state moto camping trip and this bag did it all. I was able to store everything I needed for the trip and still had the ability to expand the bag for more room. It fit very well on my detachable luggage rack and was very easy to strap down with the provided straps. It never came loose or moved either, except when I laid the bike down on a dirt road. Even then, it barely moved and I had to completely disconnect it to remove it. See photo. Removal was a breeze with the clip style straps it comes with. I rode through 2 separate hurricanes on this trip and never had an issue with wet luggage. This was all without the rain cover due to having my tent strapped to the top of the bag, which was very convenient. It looks like a good quality item and feels that was as well. I highly recommend this duffle for anyone looking for one of this size and style. This thing held up to some abuse and is still in excellent condition. We're excited to use this on future trips around the country.
