The Peak 24oz Tumbler is designed to be fully functional for both hot and cold beverages. Its built-in flip straw offers convenient, effortless sipping. Snap the straw shut and you can chug from the flap-open spout! It includes a cozy handle which provides on-the-go convenience. It is constructed using 91% post-consumer recycled 18/8 stainless steel plus all the other recycled plastic but having no compromise on style or performance at all. Durable, double-wall stainless steel vacuum construction with copper insulation allows your beverage to stay cold for up to 48 hours and hot for 12 hours. The construction also prevents condensation on the outside of the tumbler. On-trend, durable powder coating. Wide opening for easy filling and pouring - perfect for ice cubes. Fits most standard car cup holders. 24oz. Note: Drinking hot beverages with the straw is not recommended. Remove lid to allow beverage to cool.
