I have been buying these for years. We have been living at the hospital for the last few years and these are a lifesaver! I would fill the 20 ounce and the larger 32 ounce, the larger would keep my coffee hot until I was ready for it after drinking the smaller. I literally have these in every color. I would sure love to be able to buy lids only, that is my only complaint

I have owned one of these for a few years and was in need of more. I have tried just about every water/sports bottle out there and this is one of my favorites. For one, it is thin enough that it fits into my drink holder in my car. Still gives you plenty of water-not too big, not too small. It keeps water cold and ice frozen for several hours. The top rotates back and forth to open and and close which I like, but of course I do not put it into a sports bag or anything cause that kind of top could leak if tipped too much.
