The North Face's 60-liter Cobra pack is better suited for technical backcountry adventures; it's fully stocked with everything you'd need for comfort, ease of movement, and performance in harsh mountainous environments.
With an intuitive ice tool and oversized crampon storage, and a stowable helmet and ski carry, you can consider this your winter pack. The load-supportive aluminum frame is durable and athlete-tested. You can also remove the framesheet, hipbelt padding, and top lid to strip things down for lighter treks; or, as with the Osprey pack, you can accommodate larger loads with the removable/floating lids.
