2 DAYS COLD WITH ICE: Working, workouts, road trips — you’ll want this Stanley cup always by your side. Thanks to Stanley’s vacuum insulation, your water will stay cold for 11 hours, 2 days with ice. CONSTRUCTED OF 90% RECYCLED STAINLESS STEEL: This thermal flask is made from 90% recycled stainless steel. The Stanley Quencher thermal mug helps you stay hydrated with fewer refills, promoting a more sustainable, less disposable lifestyle. FLOWSTATE SCREW-ON-3-POSITION LID: With our tumbler, you choose how to sip. Use the straw for hands-free hydration or remove it for a sipping opening. The semi-covered lid makes the Quencher splash-resistant while on the go. DISHWASHER SAFE: Our water bottles with straw are designed to clean easily. The lid disassembles for deep cleaning. Every piece of this stainless steel water bottle is dishwasher safe. BUILT FOR LIFE: 'Built for Life' has been the Stanley promise since 1913, manufacturing rugged, high-performance products that last a lifetime.
