This week we’re going to be looking at all sorts of green school supplies.

First up, the Queso backpack from Earthpak, made from 98 percent recycled materials including plastic pop (some might call it ‘soda’) bottles.

It features a large main compartment but also a unique expandable cinch cord system that allows you to carry items on the outside as well. The bag also has a spinal and lumbar support system built into the back of the bag that allows for proper weight dispersion as well as helping to correct align the back for proper posture. And it comes with a fully padded laptop sleeve.

How can you say no?
