Jomddems Insulated Lunch Bag — Large Reusable Cooler Tote, 11.2x6.7x9.5 in, 3-Layer Thermal with Adjustable Shoulder Strap

The Jomddems Insulated Lunch Bag is a roomy, reusable cooler tote that keeps meals fresh or warm for hours while offering versatile carrying options and organized storage.

This insulated lunch box combines a three-layer thermal construction with durable exterior fabric, multiple pockets and a detachable shoulder strap to suit daily commutes, outdoor picnics, or weekend trips. Built with a waterproof 300D oxford shell, a 5mm pearl foam insulating core and an eco-friendly leakproof EVA liner, the bag balances performance with easy cleaning and long-term use. At 11.2 x 6.7 x 9.5 inches it accommodates full meal containers, snacks and a drink, while the extra pockets keep small essentials separated and accessible.

How long will this insulated lunch bag keep food cold or warm?

The Jomddems cooler relies on a three-layer system—waterproof oxford fabric, 5mm pearl foam insulation and an EVA leakproof liner—to reduce heat transfer and retain temperature. Performance varies with initial food temperature and ambient conditions, but the construction is designed to extend freshness or warmth for several hours. For longer temperature control, pair the bag with ice packs or pre-warmed containers.

• 5mm thick foam core for thermal resistance
• EVA lining prevents leaks and aids insulation
• 300D waterproof exterior shields against moisture
• Works better with ice packs or hot containers for extended periods

What can fit inside and how is it organized?

The main compartment is large enough for multiple meal containers, a reusable bottle and snacks, while additional pockets help keep accessories tidy. You get one main zipped section, a front zip pocket for small items, a roomy back pocket and two side pockets for bottles or tissues. This layout makes it easy to separate food from electronics and personal items.

• Main compartment fits lunchboxes, fruit and a 20–25 oz bottle
• Front zip pocket for phone, keys or utensils
• Back large pocket for chargers, notebooks or a slim tablet
• Dual side pockets for water bottles or small umbrellas

Is this lunch bag easy to clean and leak-resistant?

The interior uses an extra-thick EVA liner with heat-welded seams to guard against leaks and make spot cleaning straightforward. Spills wipe away with a damp cloth, and the waterproof outer fabric resists stains and dampness. The seam construction minimizes seepage points commonly found in stitched liners.

• Heat-welded EVA liner reduces seam leakage
• Wipe-clean interior for quick maintenance
• Durable 300D oxford outer fabric repels water and dirt

How can I carry the bag and how durable is it?

Jomddems designed three carrying styles: grab-handle, adjustable shoulder strap and tote. The detachable strap adjusts from 14" to 25" to suit different heights and carrying preferences. Heavy-duty metal zippers, reinforced buckles and a thick handle help the bag withstand daily wear without sacrificing comfort.

• Detachable shoulder strap for hands-free carrying
• Reinforced handle reduces hand strain during transport
• Metal zippers and buckles for long-lasting use

It’s ideal for those who value organization, portability and durability—perfect for daily lunches, park picnics, beach days and short road trips.
