Arc'teryx Altra 72 Backpack -

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.
