Resa 35oz Leakproof Travel Tumbler with Handle & Straw - Keeps Drinks

Our review of the Resa 35oz travel tumbler finds it best suited for commuters, gym-goers, and anyone who tosses a drink into a bag and expects no surprises. The single biggest reason to buy is its 100% leakproof U-Turn lid system that safely seals carbonated and cold drinks, so spills are a non-issue when moving between home, work, and the car. The tumbler balances insulation, convenience, and durability in a design that feels thoughtful rather than gimmicky.

Key Features

• 100% Leakproof: The patent-pending U-Turn technology seals the straw opening for truly leak-free transport, even with carbonated beverages.
• ColdKey Metal Straw: The stainless steel straw with a SoftSip silicone tip reduces plastic contact and delivers a cool, comfortable sip.
• BevGuard Insulation: The double-wall stainless steel construction keeps drinks cold for 24+ hours, making it reliable through long days.
• Built-in Silicone Sleeve: The removable silicone sleeve protects against dents and improves grip while allowing customization.
• Dishwasher Safe Parts: Most powder coated surfaces are top-rack dishwasher safe and all lids and straws can be cleaned in the dishwasher.
• Lifetime Guarantee: The product is backed by a lifetime warranty, which provides reassurance for long-term everyday use.

Who It's For

The Resa 35oz is ideal for people who need a reliable, large-capacity tumbler for daily travel: commuters, parents, and fitness fans who carry drinks in backpacks or gym bags will appreciate the leakproof lid and comfortable handle. It also fits most cup holders and works well for extended outdoor activities where consistent cold retention matters.

Those who prefer very compact bottles or only occasional single-use tumblers might find the 35oz size larger than needed, and if someone wants a hot beverage focused flask, this model emphasizes cold and carbonated drink handling rather than hot-holding performance.
