Product Features

The standout feature of this 40oz stainless steel tumbler is its thoughtfully engineered design that makes hydration more convenient, efficient, and enjoyable—whether you’re at the gym, on the road, or relaxing at home.
With an extra-wide 8.8cm mouth opening, cleaning your 40oz stainless steel tumbler is faster and easier, allowing you to reach every corner with minimal effort. The upgraded lid features a secure UFO-style snap-on lock, ensuring the straw lid stays firmly in place—even with vigorous shaking—so you can carry your tumbler with confidence.
Enjoy smooth, uninterrupted sips thanks to the 1cm-wide straw, designed to deliver a steady flow of water with no clogs or interruptions. The enlarged handle is built for comfort, offering an easy grip that makes lifting and carrying your 40oz stainless steel tumbler effortless—even when it’s full.
A non-slip silicone pad on the base helps prevent slipping and reduces noise when placing the tumbler on hard surfaces. Plus, the base is perfectly sized to fit in standard car cup holders, making it the ideal companion for travel, commuting, or outdoor adventures.
Whether you’re staying hydrated on the go or looking for a reliable, stylish tumbler for everyday use, this 40oz stainless steel tumbler delivers performance, durability, and smart design in one sleek package.
