I LOVE this pack that I received as gift, but it's the wrong size! I took it on two day hikes and although it worked, I want one fitted better to my torso.
The Osprey Exos 38 is one of the most popular lightweight packs out there. This one is a large (2500 cubic inches or 41 liters) yet weighs only 2.5 pounds! It's a perfect overnight or ultralight thru-hiking pack.
It has Osprey's famous breathable mesh "trampoline" suspension that provides amazing ventilation. If you use trekking poles, you'll love the "Stow-on-the-Go" carry system that lets you store/retrieve them while walking.

I am asking $150 firm for this pack, and for that I will also include the matching waterproof rain cover with a unique adjustable harness strap that keeps it from flipping up or falling off like elastic-only covers. (It's even better than Osprey's!)
