Osprey Atmos 50 - size L - old style, not the AG or whatever. Great lightweight pack. I walked from SF to Yosemite in it, so it's got some magic.
Used, but good condition, lots of hikes left. A few small scuffs, and there is one hole in the top pocket (pictured), but it's probably the best place to have a hole, if you have to have one. Nothing has ever fallen out of it. Everything else is in great shape and trail ready.

50$ + shipping (maybe 15 bucks? It's very light, about 3 lbs)

Small hole at the top of the top pocket - it points up, and doesn't really cause trouble.
