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

In this review of the Resa 25oz travel tumbler, the bottom line is simple: if you need a durable, truly leakproof tumbler for everyday transport of cold or carbonated drinks, this is a strong contender. The Resa stands out for its patent-pending U-Turn leak system that lets users toss a filled cup in a bag without worrying about spills. It also combines a stainless steel ColdKey straw with a SoftSip silicone tip and a removable silicone sleeve, making it practical for commuting, gym bags, and travel where reliable leak protection and long cold retention matter.

Key Features

• 100% Leakproof: The patent-pending U-Turn technology prevents spills even with carbonated beverages, giving true peace of mind when carrying drinks in bags.
• ColdKey metal straw: The stainless steel straw reduces plastic contact and stays cool for a crisp sipping experience, topped with a soft silicone tip for comfort.
• Built-in silicone sleeve: The removable silicone sleeve adds grip and protects the powder coat from dents and dings while making the tumbler easier to hold.
• Long cold retention: BevGuard insulation keeps drinks cold for 24+ hours, so iced beverages stay refreshingly cold through long days.
• Dishwasher safe parts: Most powder-coated bodies are top-rack dishwasher safe and all lids and straws can be cleaned in the dishwasher, simplifying maintenance.
• Lifetime warranty: The included guarantee means the tumbler is designed to be a long-term companion rather than a disposable cup.

Who It's For

The Resa 25oz is ideal for commuters, gym-goers, and travelers who carry cold or carbonated drinks and need a truly reliable leakproof option. Its handle and 25oz capacity suit those who want more than a sipper but still need a cup that fits many cup holders and bags.

Those who want a simple insulated mug without a straw or who primarily need a hot beverage tumbler should look elsewhere, since the Resa is optimized for cold and carbonated drinks and features a straw-based lid rather than a traditional hot-beverage flip lid.

Pros & Cons

Pros

• ColdKey stainless steel straw with SoftSip tip balances sustainability and sipping comfort.
• Removable silicone sleeve and powder coat increase durability and grip.

Cons

• The straw-style lid is purpose-built for cold beverages and may not be ideal for users who prefer a hot-beverage mug.
• Top-rack dishwasher safety applies to most powder-coated bodies, so some finishes may require gentler cleaning.
