This 22oz durable insulated bottle features a double-wall stainless steel vacuum construction with copper insulation that keeps your beverages cold for up to 48 hours and hot for at least 12 hours while also preventing condensation on the outside of the bottle. Powder coating keeps the outside of the bottle looking great and the screw-on spill resistant lid will keep your backpack dry. The bottle has a wide opening perfect for ice cubes and fits most standard cup holders.
