Like the kids in our lives, this pack sprouts from palm-sized to full-grown in the blink of an eye. Lightweight and compressible, it features a supple fabric that stuffs away into its own pocket for easy storage when not in use. The multifunctional design, with a panel loading front access zipper, makes it easy to load everything from bulky beach towels to a rain shell and lunch. The internal stash pocket (doubles as a stuffsack) secures small essentials. Supple Air Flow mesh shoulder straps stay cool in the heat and protect small shoulders from the heavier loads of school. With an interior ID label and a top carrying loop. Made from 2.1-oz 70-denier nylon ripstop with a polyurethane coating and silicone finish. Reinforced at the base with 6.3-oz 210-denier 100% nylon double ripstop that has a polyurethane coating.
