Hydro Flask 28 Oz All Around Tumbler Press-in Lid Agave - Keeps Drinks

In this review of the Hydro Flask 28 Oz All Around Tumbler in Agave, the bottom line is simple: this insulated tumbler is for anyone who needs a large, reliable cup that preserves temperature for long stretches. The 28 oz capacity handles long workdays, commutes, or outdoor activities, and the standout reason to buy is its proven TempShield insulation that keeps cold drinks cold and hot drinks hot without adding bulk.

Key Features

• 28 oz capacity: The larger volume is ideal for long days or those who prefer fewer refills, holding enough for coffee, smoothies or extended hydration.
• TempShield insulation: Double-wall vacuum insulation retains temperature for hours so beverages stay at the intended temp whether slow or fast sippers.
• Closeable slider lid: The press-in, color-matching lid slides snugly shut to reduce splashes and provide leak resistance during daily use.
• Dishwasher safe: Durable finish and stainless steel construction allow for easy cleaning in the dishwasher while preserving color.
• Cupholder friendly design: The tumbler is shaped to fit most cupholders, making it convenient for road trips, bleachers, or in-vehicle use.

Who It's For

The Hydro Flask 28 oz tumbler is aimed at commuters, office workers, parents, and outdoor enthusiasts who want a single vessel that covers coffee, iced drinks, and smoothies. Its large 28 oz size suits longer outings or those who dislike frequent refills, and the insulated walls help retain beverage temperature through a typical work shift or a long drive.

Those who want an absolute leakproof travel mug for packing into bags with fragile items or who need a screw-top locking mechanism may want to look elsewhere, since the press-in slider lid offers splash and spill resistance but has received mixed comments about staying firmly in place under heavy stress.
