I have a Zpacks Zero that I bought on here a few months back and never have taken out ---catch and release item.

31x15x5 (torso is 21" if i'm measuring right...from straps to bottom of pack)

Here is the info I was given when I bought it:

"It's a Zero in small but 5 inches added to the length making it a small medium sort of speak. In white black heavier nylon reinforced Cuben. Weight, 8.5 ounces on my scales..Has outside loops to place pad for frame, mesh outer pocket, top and bottom straps, haul loop, Cuben side pockets..About 2400 Ci including the pockets. Used it for 10 day JMT hike, used 4 nights since, and few day hikes. No rips, tears, wear I can see, naturally some minor dirt stains on the bottom."

This pack has a long life ahead of it and fits really well, I have tried on some other Zpacks and never liked how the shoulder straps fit me but this one fits nicely and does not pinch in toward my neck. PayPal gift or add 3% $115.00 shipped CONUS US only.
