The Arc'teryx Khazri 55 Backpack holds enough gear for a multi-day alpine ascent, and it strips down to nothing more than a sack with straps for fast-and-light single-push climbs. Adding only the necessary features, Arc'teryx used dual aluminum stays for increased support and a free-floating lid to let you really overload this bag. Of course, the Kharzi 55 Backpack's stays, back-panel, and lid can all be removed to shed ounces. You can even use the removable foam pad at an unexpected bivy. *Only available for US shipment.
