This is a NIKE backpack. It has a zippered pocket on the outside. Inside, there's a main compartment, a PC sleeve, and pockets for organizing small items, such as a zippered pocket. Also, there's a compartment at the bottom with a double zipper that can be used as a shoe compartment. I think it's perfect as a gym backpack. There's some minor wear and tear, but overall, it's in good condition. Color: Green系 (Green-based) Accessories: None Stains/Tears: None
