Hydro Flask All Around Tumbler 28 oz Surf Blue - Insulated Travel Mug

In this review the 28 oz Hydro Flask All Around Tumbler in Surf Blue is evaluated as a large, cupholder-friendly insulated travel mug for people who want reliable temperature retention and a clean, monochrome look. The single biggest reason to buy is its consistent temperature performance: double-wall vacuum insulation keeps hot drinks hot and cold drinks cold for hours while the color-matched press-in lid creates a streamlined, splash-resistant package that is comfortable to hold and easy to clean.

Key Features

• Insulation: Double-wall vacuum TempShield insulation maintains drink temperature for hours so slow sippers do not end up with lukewarm coffee or warm iced drinks.
• Closeable lid: The press-in, leak-resistant slider lid slides shut to reduce splashes and light leaks during commutes and outdoor use.
• Comfortable grip: The tumbler's shape and stainless steel construction are easy to hold and suited to long days when you need a large serving of coffee or water.
• Cupholder friendly: The design fits most cupholders, making it practical for driving, sidelines and travel.
• Pure taste: Pro-grade stainless steel construction prevents flavor transfer so each drink tastes fresh.
• Dishwasher safe: The tumbler and lid are dishwasher safe for quick cleanup and to preserve bright color.

Who It's For

The Hydro Flask 28 oz tumbler is ideal for commuters, long-shift workers, students and anyone who wants a large-capacity insulated cup that keeps beverages at serving temperature for hours. It suits people who prefer a single-color, stylized aesthetic thanks to the color-matching lid and surf blue finish.

Those who need a fully waterproof solution for prolonged submersion or who prioritize a lid that locks mechanically rather than slides should look elsewhere; the closeable slider is splash-resistant and reduces leaks but some users report mixed experiences with lid retention during rough handling.

Pros & Cons

Pros

• Excellent temperature retention for both hot and cold drinks thanks to TempShield insulation.
• Color-matched closeable lid and durable finish create a cohesive, attractive look.
• Dishwasher-safe design and stainless steel build make cleaning easy and prevent flavor carryover.

Cons

• Some users report the press-in lid can pop off under certain conditions, so it is not guaranteed fully secure during rough use.
