Refill. Refresh. Repeat. We poured a (practically) bottomless amount of intuitive, drinker-friendly design details into this stainless steel tumbler: Leakproof interchangeable lid, no-look-sip indicator, built-in coaster, effortless flip ‘n’ sip way to drink…the list goes on (scroll down to see it all). It goes without saying (but we’ll say it anyway) that’ll you’ll also get super long-lasting hot/cold retention. And at 12 ounces, this powerful, reusable little vessel is great for shorter days or the perfect cup of coffee.
