Recently added a SW Motech 180 Drybag to my camping setup. I needed a smaller drybag for all my food and cooking supplies. Where I was camping there was a huge concern with bears. Especially Grizzlies. The plan was to tie a drybag up in a tree. Most of my camping is in established campgrounds with the occasional backwoods site. The nice thing about the 180 Drybag is that it fits in the right side pannier perfectly. It was much more convenient being able to put it in the Pannier than tie it in a tree. There was still room for personal items like soaps, toothpaste, deodorant and the like. Now it is certainly not as safe as tying to tree but much more convenient. If you're looking for a small drybag for the back of your bike it is a great option. Very happy with it and was a great addition.
