Arc'teryx Altra 85 Backpack -

The Arcteryx Altra 85 LT Pack is an expedition pack that is loaded with technological advancements that allow it to comfortably carry heavy loads over all kinds of terrain. Ice axes, 8 days of food, oxygen tanks and the entire first season of 24 on DVD, it can effortlessly haul them all with the help of the pivoting Load Transfer Disc™. The pear-shaped Altra design holds the pack close to the body, to limit load movement and allow for extended comfort. The Wingman™ side pockets are accessible without removing the pack to prevent constant stop-and-go. The Altra 85 also offers a number of other "quality of life" features like a U shaped kangaroo pocket and a dual-zippered lid. Comfort, convenience and all-out hauling power.

The Arc'teryx Altra 85 L Backpack is an expedition sized pack that carries heavy loads comfortably for long periods over rough terrain. All packs in the Altra family feature a Load Transfer Disc that pivots to increase agility and stability on rough terrain. The Altra 85 also uses 210D nylon ripstop throughout the body of the pack. This material is a high density single ripstop fabric coated with silicone to shed moisture and increase waterproofness. Incredibly durable and tear resistant, this pack is ready for anything.

If your backpacking trips require you to measure the time in weeks and count the miles in the hundreds, it's probably time to invest in the Arc'teryx Altra 85 Backpack. The C² Suspension System reduces fatigue and load movement by keeping the pack close to your body, which allows you to move more efficiently and safely on technical terrain with a heavy load. The top lid can be extended to accommodate extra-large loads, and the burly silicone-coated nylon fabrics provide unmatched durability.
