Resa 35oz Leakproof Travel Tumbler in Lavender - 100% Leakproof

In this review of the Resa 35oz travel tumbler the bottom line is simple: if you want a carry-on cup that truly survives a tossed-in-bag commute and keeps drinks cold all day, this is worth considering. The reviewer tested it as a daily gym and work companion and found the single biggest reason to buy is its 100% leakproof straw lid, which lets you transport carbonated or iced drinks without worry. It feels substantial in hand, the removable silicone sleeve adds protection, and the included stainless steel straw with a SoftSip tip improves the sipping experience over typical plastic options.

Key Features

• 100% Leakproof U-Turn lid: The patent-pending U-Turn mechanism seals the straw path so you can toss the tumbler into a bag without spills, even with carbonated beverages.
• ColdKey stainless straw: The built-in ColdKey metal straw reduces plastic contact and keeps every sip feeling cool and clean thanks to the SoftSip silicone tip.
• BevGuard insulation: Insulation keeps drinks cold for 24+ hours, making it suitable for long workdays, hikes, or travel.
• Removable silicone sleeve: The silicone sleeve protects against dents and provides extra grip while allowing quick customization or cleaning.
• Dishwasher safe parts: Most powder coat bodies are top-rack dishwasher safe and all lids and straws are dishwasher safe for easy cleaning.
• Lifetime guarantee: The tumbler is backed by a lifetime warranty, which adds long-term value and confidence in daily use.

Who It's For

This tumbler is aimed at commuters, gym-goers, and anyone who carries a cold or carbonated drink on the go and needs reliable leak protection. The 35oz capacity and handle make it practical for longer outings or shifts where refills are inconvenient, and the Lavender color is a nice touch for those who prefer a softer palette.

It is less suited for people who primarily need a hot-beverage flask, since the focus here is on cold and carbonated drinks. If you prefer an ultra-compact cup for small cup holders or pocket carry, a smaller-capacity bottle may be a better fit.

Pros & Cons

Pros

• Dependable 100% leakproof lid design lets you carry it in bags with no spills.
• Excellent cold retention for 24+ hours thanks to BevGuard insulation.
• Sturdy handle and removable silicone sleeve improve grip and protect the metal body from dents.
• Easy to clean: lids and straws are dishwasher safe and disassemble for scrubbing.

Cons

• At 35oz it is larger and may not fit every car cup holder or ultra-compact bag side pocket.
• The powder coated body should be top-rack washed per guidance, which may be a slight care consideration.
