I have two backpacks for sale in Rogers Park, Chicago IL. 

1) Chrome backpack that has been my staple bag for the last 5 years. As the title says it is well used. However it still keeps everything dry in the main compartment. I recently had Chrome Industries repair some stitching and replace some velcro with their guarantee. (I will post photos when I get home and can take some of this bag) 

Asking $50

2) Pristine, Red, grey, and black Timbuck2 Phoenix Laptop Commuter Backpack. 

Shown here with 5 large hardback books, a pair of dress shoes size 8, and a full change of clothes. Jeans, belt, shirt, vest, socks, and underwear, with room to spare.
Separate back padded pocket for laptops, tablets, or other electronic devices.
Plenty of storage with water bottle pocket on 1 side, multiple front pockets and expandable capacity from 26L to 35L when the extra space is needed.

This has never been in the rain, slow, or inclement weather, though it does have Timbuk2's traditional water resistant material and fold over flap to keep the water out.

Asking $75

If you have any questions about the bags feel free to contact me here, or email me at hammerpjh@gmail.com (Just put in the subject line the backpack you're inquiring about) 

Thanks!
