Titan by Arctic Zone Expandable Lunch Box – Grey, 2 Ice Walls & Leak-Resistant Insulated Cooler

Whether you pack lunches for school, bring meals to the office, or take snacks on day trips, this grey expandable lunch box combines flexible storage with engineered cooling. Its layered insulation system — SuperFoam, Therma-Flect radiant barrier and two removable Ice Walls — is built to slow temperature rise. The exterior is water-repellent and the interior features an easy-clean lining treated with Microban for reduced odors and stains.

How much extra space does the lunch box provide when expanded?

The expandable design nearly doubles capacity when you open the expansion gusset, giving room for an extra container, snacks, or a reusable water bottle. When not needed the lunch box collapses flat for compact storage.

• Expandable gusset increases internal volume for bulky items
• Collapsible profile stows neatly in lockers or cupboards
• Multiple pockets for organization, including an insulated front pocket

How long will food stay cold with the included Ice Walls?

With both Ice Walls in place plus the insulation layers, the lunch box is engineered to keep contents Fridge Cold (~40°F / 4.4°C) for up to 6 hours and chilled (~50°F / 10°C) for up to 12 hours under typical conditions. Performance varies by ambient temperature and the starting temperature of the food.

• Two high-performance Ice Walls slot into exterior pockets to avoid opening the main compartment
• SuperFoam insulation and Therma-Flect radiant barrier reduce heat transfer
• Results depend on weather, packed volume, and initial food temperature

Is the interior easy to clean and leak resistant?

The interior has an Ultra Safe lining treated with Microban for protection against odors and stains and wipes clean quickly. It’s designed to be leak proof for everyday spills, but the zipper itself is not fully leak tight—use care with liquids.

• Microban-treated lining resists bacterial growth and odors
• Smooth material wipes clean with mild soap and water
• Internal seams and lining minimize leaks; zipper is not fully waterproof

How can I carry the lunch box for different activities?

The Titan lunch box adapts to multiple carry styles to suit school days, commutes or hikes. Use the top or side handles, attach the removable adjustable shoulder strap, or clip it to a backpack with the included Swing Clip for hands-free transport.

• Top and side handles for horizontal or vertical carrying
• Removable adjustable shoulder strap for over-the-shoulder use
• Attachable Swing Clip for clipping to bags or gear while on the move

If you want a lunch box that stores frozen Ice Walls separately, expands for extra items, and wipes clean easily, the Titan by Arctic Zone Expandable Lunch Box offers a balanced mix of cooling performance and practical features for daily use.
