Built for long, tough day hauls up peaks and through winding canyons.

Use the Arc'teryx Men's Altra 35 Backpack for your gear when you plan on bagging a few Colorado fourteeners during the summer months. This strong, durable, weather-resistant pack features a C² suspension system to help keep weight to a minimum and provide a stable, comfortable, and supportive pack that carries your essentials and then some during arduous feats.


  • 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
  • Ergonomically shaped shoulder straps feature 500D nylon with silicone-treated PU fabric for durability and protection against dirt, snow, and water pick-up, a Hypercell foam to provide 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, durability, and next-to-body comfort
  • Altra 35L is available in short, regular, and tall and holds everything you need for a long day on the trail or in the canyon
  • Vertical-zippered access point offers easy access to your gear
  • Extendable top lid and extension collar enable you to carry larger loads and use the Altra 35L as an overnighter when you pack light
  • Body fabric consists of 210D nylon ripstop fabric coated with silicone to shed moisture, increase water resistance, 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
  • Wingman one-handed easy access pockets store your camera or headlamp
