Backpacker Magazine picked this Backpack as 2010 Editors Choice. Here’s why.

Strap into the cool, comfortable, and adjustable suspension of the Arc’teryx Altra Backpack for your next multi-day backpacking adventure. The two sizes expand and compress to the size you need for gear-heavy weekends or long-distance trails. So whatever season or reason brings you out, the Altra 65 can get you there comfortably.

* The Advanced Composition Construction Suspension system includes two 6061 aluminum stays and a padded back panel that hold the pack’s shape
* GridLock shoulder strap adjustment system lets you custom fit the pack
* Breathable foam shoulder straps and hip-belt are covered with Spacermesh and promote evaporative cooling when weighed down
* Triple-density hip-belt pivots on the Load Transfer Disc and can be removed to trim weight
* Perforated foam back panel lets cool air through as you hike
* U-shaped front-panel access loads and unloads like a duffel bag so you can get at your gear
* Top lid and collar extend to offer seven liters of additional space
* Four compression straps with padded wings let you attach sleeping pads or jackets to the outside of the pack

The pack maybe a bit heavy for me, but it looks like a very cool pack. Weighing in at [Reg] 4lb 14oz (2200g); [Tall] 5lb 1oz (2300g)

Bottom Line: When you have a lot to carry on longer trails, please your back with the Altra.
