Introducing the Proof-O-Perk-inspired insulated bottle, a perfect fusion of coffee culture and digital scarcity that lets you show your love for exceptional brews and the Bitcoin revolution in style. Vacuum insulation is a big deal if you care about beverage temperature change. 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. Furthermore, 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.
