The Iron Flask 32 oz Classic 2.0 Tumbler is the largest from the classic 2.0 fam. While holding enough liquid to last you a while, its double-walled vacuum insulation keeps your drinks cold for 16 hours and hot for 4 hours, with no exterior sweat. Despite its larger size, it fits in most cup holders so it can accompany you wherever the day takes you. This 2.0 version of the classic tumbler is leak-proof and has a rubber bottom that doubles as a non-slip and noise-proof coaster. And it includes two different insulated lids; a splash-proof straw lid with two straws, and a 100% leak-proof flip lid, so you can choose the way you sip.
