Keep drinks at the perfect temperature from morning commute to evening workout with a 40 oz insulated bottle. Double-wall vacuum construction holds beverages cold for up to 24 hours and hot for up to 12, so coffee stays warm and water stays icy all day. A silicone-sealed press-type lid locks tight and stays leak-proof even through 360-degree shaking, eliminating worries about spills in a bag. Built from double-wall 18/8 food-grade stainless steel and Fda-certified, the flask delivers safe, pure-tasting sips with every drink. An integrated handle on the lid makes it easy to grab and carry on the go, while the generous 40 oz capacity keeps you hydrated through school, work, camping, and travel without constant refills.
