The Altra 50 LT has been discontinued. It was replaced by the Arc'teryx Bora AR 50.
When you find yourself strapping your sleeping bag, cook pot, and tent poles onto the outside of your daypack, it's time to invest in the Arc'teryx Men's Altra 50 Backpack. This pack provides enough gear space for one, two, or three nights of quiet bliss in the backcountry, and the C2 suspension system helps keep weight to a minimum while boosting comfort and support.
Historic Range: $173.40-$289.00
