Key specifications

• Material: Durable, leak-proof plastic
• Cooling medium: High-performance cooling gel

• Reusable design

To use the cooling insert, place it in a freezer for several hours until the internal gel is completely frozen. Once solid, insert the pack into your thermal bag or portable cooler alongside your food and drinks. For optimal performance, place the insert on top of the items, as cold air naturally sinks, helping to maintain a consistent temperature throughout the container.

What to consider before purchase

• Ensure the dimensions of the insert fit your specific thermal bag or cooler model
• Consider purchasing multiple units if you need to cool larger quantities of food
• Check that your freezer has enough space to accommodate the insert during the freezing process

For the best results, pre-chill your food and drinks before placing them in the cooler, and keep the thermal bag closed as much as possible to minimize heat exchange.
