The Stanley St. Patrick's Day Flowstate Quencher 40oz Tumbler Shamrock Green is a travel mug featuring a vivid Shamrock Green hue with a matching emerald-hued lid and straw. Crafted from recycled stainless steel, the Quencher Flowstate features a 40-ounce capacity and keeps drinks cold for hours.
While reusable travel mugs have become a major item since the 2010s, Stanley has been innovating products intended to last a lifetime since 1913. The Flowstate Quencher is notable for its lid with three sip options: accommodating a reusable straw, no straw, or closed tightly, and it fits in commonly sized cupholders.
Our experts feel that the best feature of the St. Patrick's Quencher is its Shamrock Green hue, which makes it stand out from other water bottles and travel mugs. The Stanley St. Patrick's Day Flowstate Quencher 40oz Tumbler Shamrock Green was released in Spring/Summer 2025 and retailed for $45.
