HOLIDAY COLLECTION: Enjoy every sip with our Everyday Tumbler this holiday season. This thermal cup maintains your beverage's temperature for up to 20 hours with ice, so you can sip a refreshingly chilled drink anytime. The insulated design prevents condensation for dry hands and surfaces. SIP WITH CONFIDENCE: The slider lid cuts down on splashes for sip ease, and the silicone base means softer landings. Durable and stackable, it’s easy to fit into your day. Keep it with you in the backyard, take it on the road, or enjoy it while lounging by the fireside with friends and family. THERMAL PERFORMANCE: With Stanley's double-wall vacuum insulation, you can count on your drinks staying at the perfect temperature. Stays cold for 5 hours and iced for 20 hours. EASY TO CLEAN: The Everyday Tumbler is dishwasher safe, making maintenance a breeze.
