A vacuum-insulated lowball tumbler with True Taste ceramic coating and a swipe-to-sip lid — built for outdoor whiskey, wine, and anything in between.

Rocky is the lowball tumbler for top-shelf sipping, al fresco. The 10oz wide opening is sized to fit a standard whiskey cube, and True Taste ceramic coating keeps every sip clean and free from metallic notes. The swipe-to-sip splash-resistant lid provides security without slowing you down, and the weighted base keeps Rocky stable on uneven surfaces.

Features

• True Taste ceramic coating — prevents metallic taste transfer; every sip tastes like your drink, not the container
• 10oz wide opening — sized to fit a standard whiskey cube or large ice sphere
• Thin, drinkable lip — natural sipping experience without the thick rim of most insulated tumblers
• Vacuum-insulated stainless steel body — keeps drinks cold for up to 24 hours, hot for up to 12 hours
• Weighted base — stays stable on tables, blankets, and uneven outdoor surfaces
• Swipe-to-sip splash-resistant lid — opens with a single swipe for easy sipping; closes securely between drinks
• Also available as a pair in The Picnic Tumbler Set
