About this item ?????????? - Every SilverAnt titanium water bottle comes with an insulating thermal sleeve. This is so that your water bottle beverages are kept hotter and colder for longer. Nevertheless, an insulating thermal sleeve doesn’t have the same longevity as titanium. After a few years, your thermal case might need replacing. Buy a fresh new thermal sleeve for your SilverAnt titanium round water bottle to replace an old or lost thermal sleeve. ????????????? - The SilverAnt replacement insulating thermal sleeve is only compatible with our 800ml/28.1fl oz titanium slim design water bottle. Purchase this thermal sleeve to keep the morning coffee warmer for longer. ??? ??????? - SilverAnt is an ISO:9001:2015 company.
