Pour a cold or warm beverage in Laken's ISO Bottle. Laken made this aluminum bottle with 7 millimeters of insulating polyethylene, so your perk-up morning beverage stays hot or an icy sport drink maintains its chill. A wide mouth makes it easy to dump ice cubes in and to clean, while the drink-safe lining on the ISO Bottle prevents leaching. Pour a cup of coffee into the 0.4-liter bottle, or a larger wake-up beverage in the 0.7-liter ISO Bottle.
