I now live in Florida, but use to live in Arizona  and needless to say it is hot in both places most of the year. My family and I always buy Contigo bottles because they really work better than any other brand we have tried. We know that we can count on it that we will have cold water in the bottle hours after we have arrived at the parks. I am sad that the Cortland 32 oz stainless steel with AUTOSEAL lid is no longer available. The new Fit model design is hard to grasp and push the autoseal on handed  for smaller hands like mine . Really would love to have that one back, or where to buy them !
