A women-specific fast-and-light pack for short backcountry trips.

The Arc'teryx Women's Altra 48 Backpack rests comfortably on your hips and shoulders from the trailhead through arduous scrambles and all the way to the perfect camping spot in a lush valley. This pack has enough gear space for one, two, or three-night backpacking trips, and it features a C² suspension system that keeps weight to a minimum while providing stability and comfort.

  • C²(composite construction) system's minimized construction lamination decreases pack weight and makes the pack sit close to the body, which minimizes load movement and backward pull and increases energy conservation
  • Women-specific design takes into account the features of a woman's body for ensured all-day trail comfort
  • Ergonomically shaped shoulder straps feature 500D nylon with silicone-treated PU fabric for durability and protection, a Hypercell foam for stability and comfort, and SpacerMesh lining for airflow
  • Twin 6005 T-6 extruded aluminum M-bar stays are rigid and lightweight to provide structural support
  • Back panel consists of HD 80 foam for support, structure, and comfort against the back while burly double-weave fabric offers strength and durability
  • Altra 48L is available in short, regular, and tall
  • Two vertical-zippered access points offer easy access to your gear
  • Extendable top lid and extension collar enable you to carry larger loads for multiple days in the backcountry or for weekend travels
  • Body fabric consists of 210D nylon ripstop fabric coated with silicone to shed moisture and provide durability and tear-resistance
  • 500D nylon silicone-treated PU fabric in high-wear areas supplies extreme durability and resists dirt, snow, and water pick-up
  • Extension collar features 100D nylon mini ripstop fabric that has incredible tear resistance and a silicone coating that sheds moisture
  • Hydration compatible (bladder not included) with a hydration sleeve external access point for convenience

Not enough support for the size

  • Familiarity: I've used it once or twice and have initial impressions

I used this pack on a two night backpack, and packed relatively light (for me).


- Great organization- some of the best I've seen with the easy access to the large compartment, two ways to access the outer compartment and an easy spot for your water reservoir.

- Minimalist


- Skinny shoulder straps that put too much weight on a too small section of shoulder, and quickly irritated a nerve. Straps seemed skinnier than my bike and snow day packs.

- Hip belt sat slightly above my hips, even though I had purchased correct size according to sizing chart. This left even more weight on my shoulders.
