For sale one Arcteryx Khamsin 52 back pack in excellent pre-owned condition. I used this pack twice to climb Mount Washington in February and it was the perfect pack for those trips but would also make a perfect lightweight thru hiking back pack. It's a Men's size medium. I love, love, love this backpack but I haven't used in awhile so it's time to go. This back pack is 52 liters expandable by 10 liters. Top loading and side loading, ice axe loops, large side pockets, ski holsters and the shovit is made of ultra durable halpolin which is perfect for things like crampons or sharp Climbing Protection. Super light weight at 4 pounds and the suspension is very comfortable. They don't make them like this anymore. Made in Canada.
