Bought this to keep a puncture repair kit and some tools that had been rattling around my top box somewhere more convenient on the bike. Bought the 4L version first which was a bit too big and I use that as tail pack when I need it. This one fits quite nicely on the frame and I can fit a ¼ drive tool set, tubeless puncture repair kit and a little flextail inflator on the bike. It's rammed full the zips are holding together well, the straps that are on it are enough to strap it to the bike or any molle type bag or webbing. It's had a month's worth/3k miles of abuse so far and is doing well. Dry bag bits nicely and does as it should. Definitely good value for money.
