The outer layer of the adult lunch bag is made of 600D waterproof and dustproof Oxford cloth, which is durable. The high-quality insulated lunch bag uses reinforced metal SBS double zippers to ensure smooth opening, tear-proof, rust-proof, and excellent durability. Good Insulation Performance: This lunch bag for men and women is lined with food-grade PEV aluminum foil, so you can put food directly into the bag.
