This backpack is a brand spankin new JanSport Carson. The most I've done with it is put some medical supplies in it. The cheapest I've seen these packs go for are $119 online: <broken link removed> I'm letting this go for $50 shipped. Its got an adjustable external frame, has an H2O pack compartment as well, and has a lot of organized space for your Bug Out needs or for your camping trip. The rest of the specs are shown in the link. E-mail me @ [email protected]
