    I love my new KOOZIE Stainless Steel Insulated 20 oz Tumbler! The KOOZIE brand keeps my drinks colder by far than any of my other insulated tumblers. I use this size all the time – at the pool, at the beach and I always use it for cold iced tea at home. I have tipped it over several times and it never leaks. This tumbler is the best I have ever purchased.
