Three to seven day, 72 litre volume trekking and backpacking pack constructed with the new C^2 Composite Construction system.DESCRIPTIONThe larger volume Altra packs (Altra 62 through 85) have a Load Transfer Disc(TM) that pivots to increase agility and stability on rough terrain and combine the C2 (Composite Construction) suspension with Gridlock(TM) shoulder straps that adjust for custom fit. The smaller volume Altra packs, (Altra 33 through 50) keep weight to a minimum by using the efficient C2 (Composite Construction) system. Trekking Near or Far Composite Construction (C2) eliminates back panel layers to reduce weight without compromising on structure or comfort. The pear-shaped Altra design holds the pack close to the body, minimizing load movement and backward pull for extended comfort and energy efficient movement under weight. Thick Skin All Arc'teryx packs use premium fabrics. The textiles used in the Altra series are chosen for durability. 210D nylon 6,6 ripstop fabric is tear-resistant and long lasting; heavier weight 500D aty nylon 6,6 protects high wear areas and resists contamination from dirt, snow and water pick-up. Suspension Details In larger volumes, 62-65L, 72-75L and 85L Altra packs offer full adjustment of the shoulder straps with GridLockTM, a unique system that adjusts straps for both width and height. In larger volumes, 62-65L, 72-75L and 85L Altra packs offer the rotating Load Transfer Disc(TM) that distributes weight to the hips on uneven terrain. Efficiency Space efficient compartments, one-handed timesaving closures and pocket configurations make Altras the lightest weight, fully featured bags in their class.

Arc'teryx put efficiency at the forefront of its Women's Altra 72 Backpack for your weekend to weeklong backpacking adventures. With a women-specific fit and a C2 (composite construction) system, this pack sits closer to your body to reduce your load's movement and backward pull so you conserve more energy on the trail. The Load Transfer Disc waist belt moves with your hips as you step over large logs, and it's removable for clean-up after the trip. GridLock shoulder straps are fully adjustable to line up with your height and width. The Spacermesh lining provides airflow so your shoulders stay dry and comfortable. The Women's Altra 72 features an HD 80 foam backpanel that offers fantastic support, structure, and amazing comfort. The aluminum M-bar stays keep the pack rigid and while staying surprisingly lightweight. Its U-zip access lets you open the main compartment entirely so you won't squish your lunch just trying to find your sweatshirt at the bottom. Its nylon ripstop body is very durable and lightweight, and Arc'teryx added ATY nylon resistance panels in critical areas. The top hydration panel is easily accessible so you don't have to unload the pack to fill it up. Also easily accessible are the Wingman pockets that hold mosquito repellent, sunscreen, or a hat while you hike. And the dual P'ax ice tool carry systems hold your axes while protecting the pick and head.
