Mine took a dump on one of these really cold days. 2 of the windows split and the zipper grabber thingies. The little handles on the zippers are whimpy. 3 of them broke. 1 on the bag 1 on each door. Clam costomer service is treating me well though, all I have to do is take pictures and send them in and they will ship me a new one. If I was to do it over I would get an insulated one. There is so much condensation it rains constantly. But yes it is handy.
