I just finished a round trip thru hike of the Ozark Highlands Trail. I had no problem with the pack. I would reccomend it to anyone.

From those grueling east coast ascents to long water carries across the desert, the Arc Air is a durable pack designed to be the ultimate combination of simplicity and function.

Featuring custom Curved Carbon Fiber Air Stays, the Arc Air creates a gap between your back and the pack for airflow and cushioning.  The frame transfers weight to your hips, keeping the weight off of your shoulders and providing a comfortable fit.

The ROBIC® fabric is highly durable and provides added abrasion resistance.

Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular add-ons, the Arc Air is sure to become your pack of choice.

For a smaller volume pack, check out our Arc Air 50L.

I’m on the Application Trail right now for the last 30 days and am 100% happy so far. Awesome pack. Probably best on trail.
