Resa 35oz Leakproof Travel Tumbler (Eclipse) - 24+ Hr Cold

In this review the Resa 35oz Eclipse travel tumbler is recommended for commuters, gym-goers, and anyone who carries a cold or carbonated drink in a bag and wants zero spills. The bottom line: its patent-pending U-Turn lid delivers a genuinely 100% leakproof straw experience, so the biggest reason to buy is simple reliability on the go. The stainless steel straw with a SoftSip tip and removable silicone sleeve add comfort and durability without compromising insulated performance.

Key Features

• 100% Leakproof U-Turn lid: Lets you toss the tumbler in a bag without worrying about spills or leaks when closed.
• ColdKey stainless steel straw: Reduces plastic contact and keeps sips tasting crisp while the SoftSip tip adds comfort.
• BevGuard insulation: Keeps drinks cold for 24+ hours, including carbonated beverages with ice, for long outings or shifts.
• Removable silicone sleeve: Protects the body from dents and gives a more secure grip and a bit of customization.
• Dishwasher safe parts: Lids and straws are safe for dishwasher cleaning and many powder coated tumblers are top-rack safe for easy maintenance.

Who It's For

The Resa 35oz suits people who need a large, reliable insulated tumbler for daily carry: commuters who stash a drink in backpacks, parents who want spill-free transport, and fitness users who appreciate the comfortable handle and straw for quick sips. The handle and capacity also make it a convenient choice for long clinic or office shifts and outdoor activities.

Those who prefer hot beverages or want a narrow slim bottle for tight cup holders should look elsewhere; this design is optimized for cold and carbonated drinks and for users who value a wider, handled tumbler over a tall skinny flask.
