Probably limited to summer travel depending on how much you pack as far as clothes and toiletries. I just responded to a question below, but it might help if i explained in greater detail what i packed. I had a heavy fleece top, a tiny rain shell, a hikerpro water filter, a 3L cambelbak bladder, a 24fl oz thermos, my wife's softshell jacket, about an old-school lunchbox sized amount of food, and about a little ziplock bag's worth of random survival type stuff, plus two apples. lol so hopefully I didn't forget anything and that helps you get a better idea of what 1950cu. in. looks like. I was able to get another lightweight fleece thrown in but there wasn't much more room left, unless you want to start leashing stuff to the outside.

I'm not the most knowledgeable guy when it comes to gear, new to it all, but i can provide my experiences. I recently bought this pack on SteepandCheap. Anxious to try it out, I filled it with a fleece, some food, camelbak bladder, and enough to fill it for a afternoon of cross-country skiing. It proved way more comfortable than expected. It rain/drizzled the entire 4 hours outside and nothing got wet. To me it seams durable enough, but I have no experience really, so can't recognize all the little extras. I see it's currently listed at $70 here on backcountry and would recommend it for that price. Very excited to keep using this pack!

Adam, this pack is not going to have the Vaude Flash torso length adjustment system. This pack has the Anatomic NT suspension system which is Energy absorbing Air Pads snuggle up ergonomically against your back, supporting a natural range of motion and ensuring excellent cushioning. A high comfort level is reinforced by the lightweight, anatomical ABS panel inside the pack’s back that ensures form stability.
