Meet the Greatyos 40 oz Tumbler with Handle and Flip Straw Lid — a high-performance travel mug built for days that demand real hydration power. This isn’t your average cup; it’s a carefully engineered hydration companion designed to keep up with busy schedules, demanding workouts, and long commutes.

Patent-protected flip straw for mess-free on-the-go sipping — our upgraded flip straw flips up when you’re ready to drink and snaps shut to seal when you’re done. This simple, leak-resistant mechanism prevents dust and airborne contaminants from getting into your beverage, even as you toss the tumbler into a bag or backpack. It’s a smart, practical feature that keeps your drink clean and ready without fuss.

40 oz capacity with all-day temperature control — fill it once in the morning and stay hydrated for the entire day. The double-wall vacuum insulation, crafted from kitchen-grade 304 stainless steel, keeps hot beverages hot for 8+ hours and cold drinks cold for 24 hours. Whether you’re sipping hot tea during a winter commute or refreshing iced coffee on a scorching afternoon, your drink stays where you want it, longer.

Leak-proof, easy-to-hold design — a twist-off lid paired with silicone gaskets creates a secure seal, so you won’t deal with sticky spills. The ergonomic, flexible handle provides a comfortable grip, making it easy to carry even when the tumbler is full of ice. Its durable construction is built to withstand daily use, trips to the gym, meetings, and weekend adventures.

Premium materials, safe and simple care — made with BPA-free materials, this tumbler preserves the purity of your beverages. It is dishwasher safe for quick cleanup, so you can spend less time scrubbing and more time enjoying your drink.
