Vacuum insulation is a big deal if you care about beverage temperature change...and no one can see if it's not just plain old H20! Double-wall construction means that hot liquids can remain hot up to 12 hours while colder choices can last a full 48 hours; that’s two whole days. Added bonus: these bottles are condensation-proof - no sweating or slipping. Built to fit standard vehicle cup holders, the stainless steel sides are both scratch and fade resistant.
