Fast, light, alpine strong

September 28, 2020

Unique in their design, the Alpha FL packs by Arc’teryx have set the bar for fast and light technical alpine travel. Highly weather-resistant, and exceedingly durable, these minimalist load haulers are specifically designed for fast-paced approaches and ascents on rock, ice or alpine terrain.


• Available in two capacities with fast and light minimalist designs and focused feature sets hardwired for climbing

• Exceptionally durable waterproof N400-AC² fabric protects gear and resists wear

• Expanded front pocket eases access, and a new internal pocket improves organization and provides secure, protected storage


Fast, light, and alpine strong, the Alpha FL Pack has been an Arc’teryx design obsession since its launch. For Fall 2020, that obsession brings evolution. The Alpha FL’s usable space now more accurately aligns with their listed capacities, and both the 30L and 40L versions extend to hold additional gear. The streamlined external pocket has been expanded for easier access, and a new internal pocket is added to securely store, organize and protect smaller items. New hardware, designed specifically for ease-of-use and comfort during fast and light alpine travel, can be found in updated top hooks, a new closure buckle, and the revised dog bones. Classic features remain, like the weatherproof and durable proprietary AC² fabric, the intuitive pull-to-open/pull-to-close main compartment entry, and the roll-top closure that helps seal out rain and snow.


The Alpha FL is built for climbers. The streamlined profile minimizes weight and stays out of the way while swinging ice tools. The pull-to-open/pull-to-close drawcord system allows easy access to the main compartment while wearing gloves, a simple strap at the top secures a rope, and six lash points and an integrated bungee system provide carry options for crampons, ice axes or a belay parka. And to manage the weight of the load, the shoulder straps have been thoughtfully designed to provide carrying comfort without adding unnecessary weight. It’s all wrapped in a minimalist, disciplined design hardwired for fast and light alpine travel.
