Resa 35oz Leakproof Travel Tumbler with Handle & Straw - Keeps Ice 24

In this review the Resa 35oz travel tumbler stands out as a practical pick for commuters, parents, and anyone who tosses a drink into a bag and heads out the door. The single biggest reason to buy is its claim to be 100% leakproof with patent-pending U-Turn technology, which actually makes it easy to carry carbonated or iced drinks without fear of spills. The build balances durability and comfort: a stainless steel body, a removable silicone sleeve for protection, and a ColdKey metal straw finished with a SoftSip tip that reduces plastic contact and makes sipping pleasant.

Key Features

• 100% Leakproof: U-Turn lid design prevents leaks so you can carry carbonated and cold drinks in a bag without spills or mess.
• ColdKey Metal Straw: The stainless steel straw with a SoftSip silicone tip gives a cooler, more sustainable sipping experience than plastic alone.
• Silicone Sleeve: The removable sleeve protects the tumbler from dents and improves grip while also allowing for simple customization.
• 24+ Hours Cold: BevGuard insulation keeps drinks icy for extended periods, so it handles long outings and commutes well.
• Dishwasher Safe Parts: Lids and straws are dishwasher safe and most powder coat bodies are top-rack safe for easier cleaning.

Who It's For

The Resa 35oz is ideal for people who need a reliable, travel-friendly bottle that survives being tossed into purses, backpacks, or car cup holders without leaking. It suits anyone who drinks iced or carbonated beverages and wants to avoid spills while retaining temperature for an entire workday or trip.

Those who want a very small or ultra-light bottle, or who prefer a lidless drinking experience, may want to look elsewhere; the Resa is built for insulation and leak protection, not minimal weight or unencumbered sipping.

Pros & Cons

Pros

• Proven leakproof lid design that works with carbonated drinks.
• Excellent ice retention thanks to BevGuard insulation for long outings.
• Durable stainless steel body with a removable silicone sleeve for protection and grip.
• ColdKey metal straw with a SoftSip tip reduces plastic contact and improves sip comfort.

Cons

• The 35oz size and insulated construction make it heavier and larger than slim bottles, which may be bulky for some cup holders or small bags.
• While most bodies are top-rack dishwasher safe, full dishwasher use depends on finish, so hand care may still be preferred for longevity.
