The Asobu Twin Pack gives you a dual-use product that can keep you both hydrated and caffeinated. The Twin pack combines a stainless steel insulated water bottle with a stainless steel insulated coffee mug. The water flask has a capacity of 30 ounces and is equipped with an easy-to-hold handle and a spill-proof straw spout. Attached to the bottle is a 20-ounce vacuum-insulated mug that can easily be separated from the bottle to use in the office at home or when getting your daily caffeine fix at your favorite coffee shop. The insulation on both the bottle and the mug will retain the temperature of your beverage for hours.
