Alpha AR 35L Backpack

Whether you're out for a day of multi-pitch climbing, alpine climbing, or ice climbing, reach for the versatile Arc'teryx Alpha AR 35L Backpack to haul and organize your gear to the summit. New to the Arc'teryx alpine line up for the season, the Alpha AR is a top performer with its newly developed fabric that provides hardwearing durability that is necessary for alpine missions. Additionally, this fabric is water-resistant and fully seam sealed to keep your gear dry when you encounter inclement weather.

At 35L that can extend up to 40L, external lash points, and intuitive zippered pockets, the pack easily accommodates all the gear you'll need for a full day in the vertical world. Stash your phone, keys, and small items in the zippered security pocket under the lid and store your guidebooks, jackets, or headlamps in the larger vertical zippered pocket on the front to keep everything organized. The pull-to-open, pull-to-close main pocket has large tabs making it easy to access with your gloved hands when ice climbing and the top strap securely holds your ropes on the approaches. Attach your ice picks and other gear to the custom webbing daisy chains and ice axe loops and haul the bag or attach it at the snow anchors with the dual haul loops and carry handles. With all these features and gear carry options, this versatile pack adapts to your needs no matter what vertical adventure you choose.

Great Mountaineering pack

I've used it several times

The quality of this pack is top-notch, which is to be expected with any product from Arc'teryx. I've now had the opportunity to use both the Alpha AR and the Alpha FL and straight out of the box most people will like this pack more as it has side compression straps and a little more burly Ice tool carry system if technical Ski Mountaineering or long ice climbs are in your near future this bag will dominate against the competition. From having sweet colors and an amazing ice tool carry system for your ice axes, as well as crampons all on the outside of the pack which, allows you to pack more important things and keep them dry in the body of the pack. The shoulder and hip belt straps are among my favorite of any pack I've used, low profile and able to carry heavy loads comfortably. Overall a 10/10 pack and will be used on all sorts of future Mountaineering and Ice Climbing objectives.
