20 oz Skinny Tumblers with Lid and Straw - Insulated Travel Cup

In this review of the 20 oz Skinny Tumblers with Lid and Straw, the bottom line is simple: this cup is for anyone who wants a reliable, compact insulated tumbler that keeps drinks cold for long days and fits most cupholders. The reviewer found that the double wall vacuum insulation delivers real temperature retention, and the slim form factor makes it easy to carry and store. While the sliding lid is convenient and splash-proof in normal use, some buyers should be aware of occasional durability concerns with the lid mechanism.

Key Features

• Food grade stainless steel: Constructed from 18/8 304 stainless steel for a rust-proof, sturdy body that is built to last and easy to clean.
• Double wall vacuum insulation: Keeps beverages hot for up to 6 hours and cold for up to 12 hours, reducing condensation on the outside for comfortable handling.
• BPA-free sliding lid: The gasket-sealed, BPA-free lid minimizes splashes and provides a sealed drinking opening that works with the included straw for easier sipping.
• Straw friendly design: Comes with stainless steel straws and cleaning brushes so the tumbler is ready for cold drinks, smoothies, and on-the-go use right away.
• Travel friendly size: The slim 20 oz shape fits most vehicle cupholders and is easy to grip, making it handy for commutes, hikes, and everyday use.

Who It's For

This tumbler is a good match for commuters, parents, and anyone who prefers a slim, easy-to-hold cup that fits in tight cupholders and small hands; it also serves well for people who want long cold retention during outdoor activities. The included stainless straws and brushes make it attractive for those who prefer reusable accessories over disposable ones.

Those who need an ultra-rugged lid for heavy daily tossing into bags or who place unusually high demands on sliding mechanisms might want to evaluate the lid durability first, as a few customers reported issues with the sliding cover over extended use.
