The Stanley 20 oz Quencher ProTour Tumbler is a compact, double‑wall vacuum‑insulated drink tumbler made from 18/8 recycled stainless steel that keeps your beverage cold for hours, thanks to its durable construction and leak‑proof ProTour Flip Straw lid that flips up for easy sipping and snaps shut when you’re done. It features classic color options with fresh graphics, a comfortable textured handle for easy carrying, and a slim base that fits most car cup holders—making it great for everyday hydration at school, work, travel, or the gym.
