Solid Grey
This is a $165 Solid Grey backpack. Made out of single piece of rigid polyprene (plastic) and would look even better painted like a ninja turtle shell.
“These unique bags feature a folding hardshell design, EPDM foam lining and straps for keeping your tablet or laptop safe and secure, two interior compartments for keeping small items handy, a built-in document clip — so your papers don’t end up smashed at the bottom of the bag — and a flexible fit, which means your back will like it just as much as your eyes do.”
