I love this bowl. It's so easy to stuff in my pack pocket or pants pocket and take with us on the trail or to the park. I was a little worried about the small opening, but my German Shepherd/Lab mix drinks out of it happily and easily. I read reviews about it being difficult to repack, but this has not been a problem for me at all. It repacks and closes, and it dries fairly quickly. I'm really pleased and plan to buy another one because this packs so small that I tend to misplace it and would like to have a couple in different travel bags.
