Resa 35oz Leakproof Travel Tumbler with Handle & Straw - Mist

In this review of the Resa 35oz travel tumbler, the bottom line is simple: it is built for people who need a truly leakproof, cold-retaining cup they can toss in a bag and rely on all day. The defining reason to buy is the Resa's patent-pending U-Turn lid that delivers a 100% leakproof straw experience for both cold and carbonated drinks, so commuters, travelers, and parents can carry beverages without fear of spills. The tumbler combines durable stainless steel, a soft silicone sleeve and a comfortable handle to make daily use effortless.

Key Features

• 100% leakproof U-Turn lid: Lets you place the tumbler in a bag or backpack without worrying about spills, even with carbonated drinks.
• ColdKey stainless steel straw: Reduces plastic contact while providing a cool, crisp sipping feel and a soft silicone tip for comfort.
• Built-in silicone sleeve: Removable sleeve helps prevent dents and improves grip while adding a layer of protection for everyday wear.
• BevGuard insulation: Keeps ice and cold beverages cold for 24+ hours, making it reliable for long days out or extended commutes.
• Top-rack dishwasher safe: Most powder-coated Resa tumblers can be cleaned easily in the top rack, simplifying maintenance and daily use.
• Lifetime guarantee: Backed by a lifetime warranty, which adds confidence in the tumbler's long-term durability and build quality.

Who It's For

The Resa 35oz is ideal for commuters, parents, and travelers who need a large-capacity tumbler that fits cup holders, keeps drinks cold all day, and can be carried in a bag without leaking. Its comfortable handle and sizeable capacity make it a good pick for people who prefer to sip throughout long outings or who switch between water and carbonated beverages.

Those who mostly drink hot beverages or who require a smaller, pocketable bottle should consider other styles; the Resa is optimized for cold and carbonated drinks and is larger than typical day-to-day mugs.
