Specifications ■ Backpack and cooler in one ■ Insulated base compartment can hold up to 12 cans and keep them cold for over 8 hours ■ Large main compartment with mesh pockets for storing groceries, clothing, and gear ■ Front zipper pocket with two mesh pockets and a key fob ■ Two external stretch mesh pockets ■ Two front slash pockets ■ Shoulder straps that fit the shoulders I bought this for camping because it can keep things cold, but I ended up not using it for camping. I only used it during the summer expo and a parent-child field trip. I found it useful for storing not only food in the cooler section, but also mobile chargers and cameras. Since shipping costs will be added to the price, I cannot offer a discount.
