30L Large Capacity Cooler Insulated Soft Cooler Camping Outdoor Popular [Radweather] Bag, 5-Layer Construction, Bag, Box, & Bag, (30 liters/Navy)

Five-layer structure for powerful heat and cold retention: The five-layer structure of 600D polyester + non-woven fabric + 5mm thick foamed polyethylene + non-woven fabric + PEVA effectively blocks cold and warm air, keeping cold things cold and hot things hot for a long time. Performance tests conducted by an external organization have proven its high heat and cold retention performance. The Japan Textile Products Quality Technology Center conducted tests on heat and cold retention performance. The test compared how the temperature of a PET bottle placed in this cooler/warmer bag and an uninsulated PET bottle changed over time in high and low temperature environments. The results showed that the cooler bag maintained the appropriate temperature for a longer time, by about three times. The graph makes this clear at a glance.
