I have a Kodiak backpack for sale. It is a wonderful knapsack, I have utilized it a couple of times as well as it is still in almost ideal health condition. The pack itself has a compartment for a resting bag as well as the rest of the pack has a whole lot of room for a tent, mattress as well as clothes. If a sleeping bag is not needed you could open up the area to have the whole knapsack to put your work in. There are zippers on the side for side access to obtain at work on the base and also the cover of the pack has plenty of storage for smaller sized factors like toothbrushes, toothpaste etc. The measurements are 30H x 16W x 12D. $50.00 is a steal for this.
