Meet the Twistie Tumbler — your new daily hydration co-pilot. Available in 22oz and 32oz, this PURE Pristine tumbler 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 lid is splash-proof and leak-proof, paired with a BPA-free flip straw that means business. Keeps drinks ice-cold for up to 36 hours or steaming hot for up to 8. Built for coffee runs, gym sessions, road trips, and every adventure in between.
