Klean Kanteen makes this durable line of 18 ounce stainless steel water bottles. Comes with a choice of cap, loop, sport, sippy or flat, and a neoprene tote is included to help keep the contents of the bottle warm or cold and keep the bottle itself looking nice.
Neoprene is the same material used for wet suits, it is a layer of a flexible foam like material coated on both sites with cloth. It makes a very durable covering that is also insulating. It is important to remember that neoprene will act as an insulator, but it is not the same as having a vacuum insulated bottle in terms of hold times on temperature. It is, however, much better than having no cover at all and Klean Kanteen rates the hold time at up to 3 to 4 hours, which is reasonable when compared to other products. Neoprene also has the advantage of providing padding for bottles that are given to children or youngsters.
