[The Secret to Long-Lasting Warmth: Four-Layer High-Quality Insulation] The outer layer of the cooler box is made of 600D Oxford fabric, which is waterproof, abrasion-resistant, and fade-resistant. The second layer is made of 5mm extra-thick EPE material, providing excellent heat retention, cold retention, and insulation. The third layer is made of high-quality, environmentally friendly non-woven fabric, and the fourth layer is lined with PEVA. The internal aluminum foil interface is hot-pressed for superior airtightness. This cooler bag is durable and highly functional. Its four-layer structure allows for unprecedented combinations of cold storage, refrigeration, and freshness. [Notes for maintaining cooling power] 1. Put one ice pack inside the cooler box to cool it, sandwich the food between the top and bottom, and do not leave any extra space. 2. Make sure the inside of the cooler and the food are thoroughly cooled before use. 3. It is best to place the ice pack at the top of the cooler bag. 4. Limit the number of times you open and close it. 5. Avoid direct sunlight; it is recommended to store it in the shade. 6. Wash and clean after use. Do not machine wash or spin-dry.

The full-length metal double zipper is smooth and durable. The shoulder strap is made of nylon and adjustable in length, with a hardware buckle design for added durability. The thick shoulder pad provides a wider contact area, reducing strain on the shoulders by evenly dispersing force. The included shoulder sling allows you to carry the cooler hands-free. This multifunctional cooler box can be used for outdoor storage or everyday storage. [Lightweight, portable, and essential for outdoor activities] When not in use, the cooler bag can be folded for space-saving storage, measuring just 36 x 32 x 7 cm.
