20 oz Tumbler Double Wall Vacuum Insulated Tumbler - Keeps Hot & Cold

In this review of the 20 oz tumbler from Eyasure the bottom line is simple: it is a dependable everyday travel cup for people who want reliable temperature retention and a durable, attractive finish. The single biggest reason to buy is the double wall vacuum insulated construction that keeps cold drinks chilled for many hours while holding hot beverages for several. The tumbler is made from 18/8 food grade stainless steel, includes a NO BPA transparent lid, and arrives powder coated in a vivid hot pink when ordered in that color variant.

Key Features

• Premium material: 18/8 food grade 304 stainless steel construction provides a rust resistant and durable vessel for daily use.
• Insulation: Double wall vacuum insulation helps keep beverages hot for over 3 hours and cold for over 9 hours during commutes or outings.
• Leak-resistant lid: Comes with a NO BPA transparent lid that lets you see the drink level and helps prevent spills when on the go.
• Powder coated finish: Non-toxic frosted powder coating resists wear and accepts laser engraving or vinyl decals for personalization.
• Car friendly size: The 20 oz capacity and smooth tapered body are designed to fit most car cupholders and are easy to hold.
• Gift ready packaging: Packaged in a cardboard box, it is suitable as a gift for holidays or special occasions.

Who It's For

This tumbler suits commuters, parents, and anyone who wants a medium-capacity insulated cup that fits most car cupholders and holds both hot and cold drinks well. It is particularly good for people who value a sturdy stainless steel build and a powder coated finish that can be personalized.

Those who need a very large capacity mug or a complex lid system for frequent bubbling drinks should look elsewhere; also buyers seeking a completely rigid, unbreakable lid should note some users reported mixed experiences with lid longevity.
