Wine, but make it portable. The Halfsies Stemless Wine Tumbler is a 16oz insulated stainless steel companion for backyard hangs, beach days, boat decks, and “I'm-not-driving” book clubs. This PURE Pristine pour brings a fully 18-8 stainless steel build, double-wall vacuum insulation with a thermal copper lining, and our patented SiSA™ antimicrobial coating. SiSA™ uses the natural antimicrobial properties of silver — not chemical additives — to eliminate 99% of microbes on the drinkware's surface. The twist-on flip-top lid is splash-proof and leak-proof. Keeps rosé crisp, reds just right, and zero shattered glassware in sight.
