Arcteryx Cierzo 35 Backpack

Created for single push ascents and ridiculously lightweight alpine climbs, the Arc'teryx Cierzo 35 Backpack holds just want you need and adds only a scant 20oz to your total gear weight. As if this Arc'teryx pack weren't light enough already, the back panel, waist belt, compression sling, ice axe loops, and even sternum strap can be removed to shave weight even further. The Cierzo 35 Backpack includes a 40mm webbing waist belt to add support without interfering with your climbing harness. Style number 5811
