Customize Large Capacity High Quality Picnic with Foil Film Custom Size Ice Cream Insulated Cooler Bag Insulated Thermal Bag

Many use thick layers of foam or specialized insulating fabrics that can maintain the temperature of your food and drinks for hours. For example, if you're packing a picnic lunch with cold sandwiches, fruits, and beverages, a well - insulated grey cooler bag will ensure they stay fresh and cool until it's time to eat. Some models can even keep ice from melting for an entire day, depending on the external temperature and usage.

Made to withstand the rigours of outdoor use, grey cooler bags are constructed from tough materials. The exteriors are often crafted from water - resistant and tear - resistant fabrics like nylon or polyester.
