School Bus Backpack: This bag has 1 big opening at the top, inside is an hollow chamber for storage with one small internal compartment. On the outside is one small zippered pockets for holding pencils and wallets and other little knick-knacks.
Padded back: Padding, about 1cm thick, with mesh lining gives users extra comfort, protection and wicks away some of the sweat that comes along with hiking up a mountain with 30lbs of gear on your back.
Chest compression strap: This strap, when correctly positioned, sits just above the sternum, and helps the shoulder straps and bag stay in place during activity. The elastic strip won't restrict movement and breathing.
Bottom Reinforcement: Extra durable material at the bottom of the bag gives strength where its needed most, preventing gear from disappearing through holes and tears.
Compression straps: The compression straps on both sides of this bag take up extra room so the gear in the bag doesn't slide around. They also make the bag smaller if a lighter load is being carried for the day.
Mp3 pocket: A small, secure pocket with a small slit for the routing of an earphone cord, to keep in touch with the music world and less in touch with the actual world.
Side Zippered Pocket: A side pocket will hold some small trinkets and a smelly pair of socks, so they are easy to find and keep the rest of the bag from smelling.
