Resa 35oz Leakproof Travel Tumbler in Kiwi - 24+ Hour Cold

In this review we look at the Resa 35oz travel tumbler in Kiwi to see who benefits most and whether it lives up to its leakproof claim. The bottom line: this tumbler is best for commuters, parents, and anyone who tosses a drink in a bag and needs confidence it wont spill, because its patent-pending U-Turn lid delivers a genuine 100% leakproof seal that works with cold and carbonated beverages. The combination of a stainless steel straw with a SoftSip tip and a silicone sleeve also makes it a durable, comfortable daily companion.

Key Features

• 100% Leakproof U-Turn technology: The patent-pending lid design prevents spills even with carbonated drinks, so you can carry the tumbler in a bag without worry.
• ColdKey stainless steel straw: The metal straw reduces plastic contact and provides a cool, clean sipping experience while the SoftSip silicone tip adds comfort.
• Built-in silicone sleeve: A removable sleeve cushions the body against dents and gives extra grip for easier handling on the go.
• BevGuard insulation: The double-wall insulation keeps drinks ice-cold for 24+ hours, making it suitable for long days and outdoor use.
• Dishwasher safe components: Lids and straws are dishwasher safe and most powder-coated tumblers tolerate top-rack cleaning for easier maintenance.
• Lifetime guarantee: The Resa line is backed by a lifetime warranty, so it is intended to be a long-term drinkware choice.

Who It's For

The Resa 35oz in Kiwi is ideal for daily commuters, parents, hikers, and anyone who needs a large cold beverage that can safely ride inside a backpack or tote without leaking. The handle and sizable capacity make it convenient for long shifts, workouts, or outdoor activities where refills are limited.

Those who prefer hot beverages only or want an ultra-compact cup for cup holders in compact cars might look elsewhere; this 35oz design is geared toward cold and carbonated drinks and larger carrying capacity rather than minimal footprint.

Pros & Cons

Cons
