Summit lovers and and mountain hikers alike know that long, tough days in the backcountry require a durable and capable pack. Arc'teryx knows this too and created the Altra 33 for all your adventuring needs. The Altra 33 is constructed with bomber 210D nylon ripstop, giving you peace of mind as you bushwhack up use trails or scamper through slot canyons. C2 composite construction keeps the pack weight close to your body, allowing you to conserve energy for your summit bid rather than waste it carrying things inefficiently. The ergonomically shaped shoulder straps paired with the SpacerMesh lining allow for airflow, ensuring comfy carrying without sweating through your layers. Side compression straps, an adjustable top lid, and extension collar let you customize your pack size, allowing the pack to function as an overnight-er for lightweight packers or a larger pack for the luxury day trips. The smartly placed vertical access zipper makes accessing gear a cinch and Wingman one-handed side pockets keep your headlamp and camera close at hand so you're never left in the dark. The Double-chambered top lid keeps your first aid kit and snacks organized for the day and an internal zippered pocket keeps your keys or wallet safely stowed away. When you are nearing the top and an ice field guards the final summit slog, you'll appreciate the Dual P'ax ice tool carry systems which enable one-handed access to your tools. Weekends are precious, so don't waste them adventuring with sub-par gear. Invest in the Altra 33 Backpack and find a partner just as capable as you are for all your exploration.
