I've owned a large briefcase and medium water bag, but realized that I needed something smaller. The large briefcase was bulky when I didn't have much on me. But I'd often find it too small when I had a lot to carry. The waterbag was just too much bag to carry every day. I bought it before the small size was introduced. I had settled on getting the small one but then saw the large dry bag. I was able to get it before the price increase. But it's still almost half the price as the small waterbag. I think it's a keeper, really nice size whether I have a lot or a little on me. It's not as easily accessible as the briefcase but I can get used to it. My other bags were dark coffee brown, decided to go with chestnut and really loving it. Here are some pics w/o the liner.
