Setting up camp for a few nights (or longer), but need a pack for a summit push? The Arc’teryx Cierzo 25 is a great choice. Super lightweight—one ounce shy of a pound—and minimalist, the unisex Cierzo can easily haul a down puffy, outer shell, lunch, a camera, sunscreen, climbing harness, extra pair of shoes and more. It has plenty of lashing options including ice-axe loops and a compression cord that wraps the entire bag and pulls the load close to your body. Plus, the entire pack stuffs into its top lid, compressing down to the size of a football. The thin foam frame sheet is removable to make it even lighter and less bulky—though you sacrifice back comfort—or, as the company touts, it can be used as an emergency sleeping pad. But it is a minimalist pack. That means neither an internal bladder hanger nor hose port, and no external water bottle pockets like you’d find on more full-featured packs.
