Load range - Not an exact science but a combination of torso sizing, hipbelt sizing and stiffness, harness sizing and stiffness, frame type, framesheet type, stay type and intended use. Load range will vary based on the user, their experience, bone structure, body fat/muscle mass and their perception of comfort or penchant for suffering. Load ranges provide a starting point to help you determine what level of comfort you can expect from our packs given a specific load. This makes it easy to compare multiple packs and make the right decision for you based on the amount of gear you plan to carry.

AirScape™ backpanel -  Lightweight, precision cut and accordion spread mesh-covered 3D foam that keeps the pack's weight close to your body for stability, provide cushioning and additional ventilation for a comfortable gear-carrying experience.
