Hydro Flask 28 oz All Around Tumbler — Press‑In Closeable Lid, TempShield Insulation

The Hydro Flask 28 oz All Around Tumbler with Press-In Lid is a large, double-wall vacuum insulated cup that keeps beverages hot or cold for hours while offering a closeable lid to reduce splashes and retain temperature.

This 28-ounce All Around™ Tumbler balances generous capacity with a thoughtful, cupholder-friendly shape. Made from pro-grade stainless steel with TempShield insulation, it preserves beverage temperature and resists flavor transfer. The Closeable Press-In Lid slides securely to help prevent spills and makes sipping thicker drinks or hot coffee more convenient. Built for everyday carrying, it’s dishwasher-safe for easy cleanup and designed to fit most vehicle and lawn-chair cupholders.

How long will it keep my drink cold or hot?

The double-wall vacuum construction with TempShield insulation slows heat exchange so cold drinks stay chilled and hot drinks stay warm much longer than a single-wall cup. Performance varies with external conditions and how often you open the lid, but the insulation maintains usable temperature for many hours.

• Double-wall vacuum insulation reduces heat transfer.
• TempShield keeps cold and hot temperatures stable.
• Minimal flavor carryover from durable stainless steel interior.

How does the press-in closeable lid work and is it leak resistant?

The Closeable Press-In Lid slides into place over the tumbler opening and can be pushed closed to cover the sip area, helping to block splashes and reduce heat loss. While it’s designed to be leak-resistant for everyday movement and minor spills, it is not a fully sealed, submersion-proof cap.

• Slide-to-close mechanism covers sip opening quickly.
• Built to limit splashes during walking and commuting.
• Not intended as a fully waterproof or pressurized seal.

Will it fit my car cupholder and is it comfortable to hold?

The 28 oz tumbler has a tapered base tailored to most standard cupholders and a balanced profile that sits steady in vehicles, on stadium seats, or on picnic tables. Its rounded sides and the stainless-steel finish make it comfortable to grip, even when filled to the 28-ounce capacity.

• Tapered base designed for most cupholders.
• Stable shape reduces tipping while driving or walking.
• Ergonomic body for comfortable carrying and sipping.

How easy is it to clean and will it stain or retain flavors?

The tumbler’s pro-grade stainless-steel interior resists staining and flavor retention better than plastic-lined cups. Both the cup and lid are dishwasher-safe for convenient cleaning, though hand-washing can extend the finish’s lifespan and remove residue from crevices more thoroughly.

• Stainless-steel interior minimizes flavor transfer between drinks.
• Dishwasher-safe for simple, routine cleaning.
• Hand-wash recommended for longer finish preservation and lid parts.

Who is this for? The Hydro Flask 28 oz All Around Tumbler with Press-In Lid suits people who want a larger-capacity, insulated cup they can carry through a commute, to work, or on outdoor activities without frequent refills. It’s ideal for coffee drinkers, smoothie fans, and anyone who needs reliable temperature retention with a practical, closeable lid and a cupholder-friendly shape. If you want durable stainless steel, easy cleaning, and a splash-limiting lid for everyday use, this tumbler fits those needs.
