Those stackable, disposable red plastic cups may be good for a game of flipcup or beer pong, but not much else. If you’re looking for an escape from crushable, disappointing cups — which, let’s face it, ain’t exactly ideal for a camping trip or insulation anyway — it’s time to stake your claim: the 16oz Stanley Adventure Stacking Vacuum Pint will keep your brew ice cold for hours, will never rust and stacks neatly to save space in your mess kit or kitchen cabinet. Stack ‘em high, bottom’s up.
