Backpacks For High School

Add inline skate wheels and a pull handle, and you've got a highly portable backpack. Shoulder straps are still an option, though, for those times when wheels would just get in the way. An earlier version of the Classmate design was included in a 2003 Good Housekeeping list of "The Best School Backpacks". Good Housekeeping called it a "back-saving bag" and noted the sturdiness of the pull handle.
The "High Sierra Swell" provides compartments designed for easy access to MP3 players, PDAs, and cell phones while also featuring an expandable design and S-shaped straps for comfort.
