Resa 25oz Leakproof Travel Tumbler with Handle & Straw - Guava

In this review of the Resa 25oz travel tumbler the bottom line is simple: it is built for people who want a truly leakproof, everyday cold cup they can toss in a bag without worry. The reviewer found the patent-pending U-Turn lid design delivers on the promise of being 100% leakproof for cold and carbonated drinks, while the ColdKey stainless steel straw plus SoftSip tip make sipping comfortable and feel less plastic-forward. For commuters, parents, and anyone who carries a drink in a purse or backpack, this tumbler solves the single biggest pain point: spills.

Key Features

• 100% Leakproof: The U-Turn lid design seals securely so you can carry cold and carbonated beverages in a bag without spills.
• ColdKey metal straw: The stainless steel straw reduces plastic contact and stays cool to the touch for a crisp sipping experience.
• SoftSip tip: The silicone tip adds soft comfort and prevents harsh contact with teeth while sipping.
• Built-in silicone sleeve: The removable sleeve protects against dents and adds grip and customization to the tumbler body.
• 24+ hours cold: BevGuard insulation keeps drinks icy for long days and performs well with ice and carbonated beverages.
• Dishwasher safe and warranted: Lids and straws are dishwasher safe, many powder coated tumblers are top-rack safe, and the tumbler is backed by a lifetime warranty.

Who It's For

The Resa 25oz is ideal for daily commuters, parents, or travelers who need a dependable cold tumbler that survives being tossed into a bag and keeps drinks cold all day. Its leakproof lid and carry-friendly handle make it especially useful for anyone who alternates between a backpack, tote, or car cup holder.

Those who prefer simple open-top bottles for hot beverages or who need a very wide mouth for on-the-go smoothies may want to look elsewhere, since this model is optimized for cold and carbonated drinks with a straw and sealed lid rather than for hot beverage sipping or very thick liquids.

Pros & Cons
