Like the kids in your life, the Patagonia Kids' Lightweight Backpack 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 multi functional design, with a panel loading front access zipper, makes it easy to load everything from bulky beach towels to a rain jacket and lunch. The internal stash pocket, which doubles as a stuff sack, secures small essentials. Supple Air Flow mesh shoulder straps stay cool in the heat and protect small shoulders from the heavier loads of school.
