Resa 25oz Leakproof Travel Tumbler (Eclipse) - 100% Leakproof Straw

In this review of the Resa 25oz travel tumbler the bottom line is simple: this is a travel cup for anyone who wants a true leakproof straw tumbler that also keeps drinks cold all day. The Resa stands out because it pairs a genuinely 100% leakproof lid with a stainless steel ColdKey straw and a soft silicone tip, so users who toss a full drink into a bag or purse without worrying about spills will find it especially useful. The review focuses on daily commute use, active days out, and anyone who drinks carbonated beverages on the go.

Key Features

• 100% Leakproof U-Turn lid: The patent-pending U-Turn mechanism prevents spills from both cold and carbonated drinks, meaning you can store the tumbler upright or upside down in a bag without leakage.
• ColdKey stainless steel straw: The metal straw reduces plastic contact and gives a cool, clean sip, finished with a SoftSip silicone tip for comfortable drinking.
• Built-in silicone sleeve: The removable sleeve protects the powder-coated body from dents and adds grip for easier handling while traveling.
• BevGuard insulation: Insulation keeps drinks cold for 24+ hours, so ice and cold beverages maintain temperature through long days.
• Dishwasher safe components and lifetime warranty: Most powder-coated bodies are top-rack dishwasher safe and all lids and straws can be cleaned in the dishwasher, with a lifetime guarantee for long-term use.

Who It's For

The Resa 25oz is ideal for commuters, parents, and travelers who need a dependable leakproof tumbler that works with carbonated drinks and ice. People who carry drinks in purses, backpacks, or gym bags will appreciate the secure lid and the ability to toss the cup into a bag without fear of spills.

Those who prefer very small mugs or want a thermal bottle for hot beverages only should look elsewhere; this design and insulation are optimized for cold and carbonated drinks and the form factor is a medium-large tumbler rather than a compact flask.
