Zojirushi Mahobin SX-DN60-AC is a 20.3 fl oz (600 ml) stainless steel vacuum tumbler designed to keep drinks hot or cold while staying comfortable to hold.

Built around Zojirushi's vacuum double-layer construction, this clear blue tumbler combines temperature control, a smooth drinking rim and a low-maintenance matte interior. Its wide 3.0-inch mouth makes filling and cleaning straightforward, while the insulated body prevents condensation with cold drinks and stays cool on the outside when filled with hot liquids. The mug's shape and finish prioritize everyday usability for commuting, office desks and home use.

How does this tumbler control temperature effectively?

The Mahobin uses stainless steel vacuum double-layer insulation to reduce heat transfer, slowing cooling for hot drinks and warming for cold drinks. The thick insulated walls and tight construction create a barrier that stabilizes beverage temperature for hours.

• Vacuum double-layer steel keeps heat and cold locked in.
• Insulated exterior prevents hot surfaces and internal condensation.
• Durable construction maintains thermal performance over repeated use.

Is it comfortable and easy to drink from and clean?

Yes — the tumbler features a smooth mouth designed to be gentle on lips and a wide opening that simplifies pouring, scooping ice and hand-cleaning. The interior's matte finish hides minor scratches and residue, reducing the need for meticulous upkeep.

• Smooth rim for comfortable sipping.
• Approx. 3.0-inch (7.5 cm) wide mouth for easy filling and cleaning.
• Matte interior minimizes visible wear and staining.

What are the dimensions, capacity and care guidelines I should know?

The tumbler measures roughly 3.3 x 3.3 x 7.1 inches and holds 0.60 L (600 ml / 20.3 fl oz). It’s designed for hand washing; avoid dishwashers and dryers to preserve seals and finish.

• Product size: 3.3 x 3.3 x 7.1 in (8.5 x 8.5 x 18 cm).
• Capacity: 0.60 L (600 ml / 20.3 fl oz).
• Not dishwasher or dryer safe — hand wash recommended.

Will the tumbler sweat or get hot on the outside?

No — the insulated double-layer design resists external condensation with cold beverages and prevents the outer surface from becoming uncomfortably hot when filled with hot drinks. This makes it convenient to carry in bags and set on desks without coasters.

• Condensation-free exterior with cold drinks.
• Exterior stays cool with hot contents for safer handling.
• Smooth, non-slip profile is easy to grip and store.
