Black Diamond has introduced an extensive line of well-engineered backpacks during the past two years. Since Black Diamond is a climbing oriented company, many of their packs are designed to directly or indirectly support climbing. However, some of the packs in their line are designed for backpacking. We previously reviewed the lightweight Infinity 60 and Innova 50 backpacks, which feature Black Diamond's innovative ergoACTIV freedom of movement suspension system.

The Axiom 40 is a lighter weight and smaller volume internal frame backpack designed to comfortably carry moderate loads. It intrigued me because of its light weight, clean design, useful feature set, freedom of movement suspension, and optimum volume for weekend lightweight backpacking. This review will assess its performance and compare it with other sub-3-pound internal frame backpacks.
