Zojirushi Stainless Mug travel thermos 20 oz — Beige Gold, vacuum insulation & leak‑lock lid

Zojirushi Stainless Mug is a 20‑ounce vacuum‑insulated travel mug in beige gold that keeps drinks hot or cold for hours while staying lightweight and easy to clean.

This 20‑ounce Zojirushi stainless mug combines durable stainless steel construction with precision vacuum insulation and a compact, lightweight body. Designed for commuters and anyone who wants reliable temperature retention, the mug uses a tight flip‑open lid with a safety lock and a two‑step release to reduce splatter. The interior is coated for easy cleaning, the stopper disassembles for thorough hygiene, and a 1‑5/8" wide mouth accepts ice and simplifies pouring. Temperature tests show strong heat and cold performance, and Zojirushi backs the mug with a five‑year heat‑retention warranty.

How long will this mug keep my beverage hot or cold?

The vacuum insulation is engineered to hold temperatures for many hours. In independent-style testing the mug retained 190°F at one hour and 163°F at six hours for hot liquids, and measured about 46°F at six hours for cold beverages.

• Hot retention: 190°F at 1 hour; 163°F at 6 hours
• Cold retention: approximately 46°F at 6 hours
• 5‑year warranty covering heat retention performance

What features stop spills and make drinking easier?

The lid has a tight flip‑open design with a safety lock to prevent accidental opening. A two‑step lid release reduces splashing by allowing built‑up condensation to settle, while an air vent in the mouthpiece promotes smooth, controlled flow.

• Flip‑open lid with lock prevents unintentional openings
• Two‑step release reduces stopper spray when opening
• Mouthpiece air vent delivers steady pour without gushing

How do I clean and maintain the mug?

The stopper disassembles so you can reach internal crevices, and the interior has a nonstick coating to make washing quicker. Use warm soapy water for daily cleaning and remove the stopper components for occasional deep wash; avoid abrasive cleaners to protect the coating.

• Disassemblable stopper for thorough cleaning
• Nonstick coated interior wipes and rinses easily
• BPA‑free plastic parts and stainless steel body for durability

Will this fit in my car cup holder and accept ice cubes?

The mug’s compact, ultra‑light body was manufactured to be space‑efficient while holding a full 20 ounces. The 1‑5/8" (4 cm) mouth allows most standard ice cubes and makes refilling simple; its slim profile suits many cup holders, but check your vehicle’s holder dimensions for a precise fit.

• Capacity: 20 ounces (approx. 591 mL)
• Mouth opening: 1‑5/8" (4 cm) wide for ice and pouring
• Ultra‑lightweight body designed for portability

Who is this for: The Zojirushi Stainless Mug is a smart choice for commuters, students, outdoor enthusiasts, and anyone who needs long‑lasting temperature control in a compact, reliable bottle. It’s especially useful for people who prioritize spill prevention, easy maintenance, and a lightweight carry option with proven heat and cold retention backed by a five‑year warranty.
