That cozie video reminded me of the Stainless bottle I take to work every night. It IS more costly than the 4-5 dollar Wally World bottles, but it is also much better made IMHO.

I have had it now for about 3 years or so and it has been droppped, kicked and left out to freeze, NO PROBLEMS to report. If you want to look at up to a ONE HALF GALLON Stainless steel bottle, check these guys out. (They also have insulated up to 20oz.).
