Insulated lunch bag with cooling function, 15 liters | Stornfield

Lunch warm packed, everything is lukewarm and damp upon opening.

The lunchbox leaks, the sandwich is mushy, and the backpack smells like yesterday. Anyone who brings food to work, the beach, or a picnic every day knows this. The large insulated lunch bag keeps food and drinks at temperature for up to 5.5 hours, protects against moisture thanks to its leak-proof inner lining, and can be easily loaded with the wide two-way zipper. The result: everything tastes just as good at lunchtime as it did when packed.

Advantages

• No more lukewarm lunches: The 3-mm foam insulation keeps the temperature stable for over 5.5 hours, so no one has to bite into cold coffee or warm yogurt anymore.
• No wet bags or sticky bottoms: The leak-proof PEVA inner lining reliably contains liquids, even when ice water melts or soup expands.
• No searching for keys in the main compartment: Separate front and side pockets keep keys, headphones, and snacks within reach without having to open the main compartment.

Usage

1. Fill: Open the zipper on both sides and insert the container upright to prevent spills or leaks.
2. Store: Place small items like keys or headphones in the front or side pockets, adjust the shoulder strap as needed.
3. Clean: Wipe the inner lining with a damp cloth, simply dab the outer fabric – no extensive cleaning required.

Pro Tip: Place a small freezer bag of ice at the very bottom before filling – the combination of ice block and foam insulation significantly extends the cooling effect beyond the 5.5 hours.
