Our Hot/Cold Insulated Drink Canisters keep your cold drinks cold and warm drinks warm. Period. Keep your water cool on that long hike, at your office desk; keep the tea and coffee hot on your daily commute, or a weekend road trip. Attractive and very portable, the bottle is 17 oz., it’s 8" tall. Made of lightweight aluminum, with a stabilizing foam bottom which doubles as a coaster. It’s easy to clean, with no hard-to-reach parts that gather mold, like straws or pumps. The mouth is just the right size, so the drink flows easily. Unscrew the top, drink it down. Simple.
