The Tortuga daypack comes with two side compartments for your water bottles or any other small items and a mesh pocket in the front, where we like to stuff an extra jacket or towel when we travel. There is a small pocket near the back, where we like to put my keys, credit cards, and other small items, and the large pocket contains a laptop compartment and lots of space for your clothes, books, snacks, camera, and anything else you may choose to bring with you on your adventures!
