Comments about Jansport Jansport Air Penny Pack:
I purchased this as a bookbag. I also wanted a second compartment for lunch and gear. It turns out the second compartment functions as a very large pocket-the bottom of which forms the bottom of the pack; it's not reinforced. This pocket-compartment has a different material that is a greyish color and has a "high-tech" feel. There is a laptop sleeve in the main compartment and plenty of zipped pockets and accessory pockets in the second compartment.
