Pivoting Backpacks: Black Diamond's Octane

In other words, as one side gets longer, the other sides gets shorter allowing the weight to balance from the right to left. It’s the perfect backpack for trips along rough and uneven trails.

One main feature that stands out is the zipper is on the top which allows for an efficient way to pack and organize your gear.

Loaded with a breathable mesh on the hip belt and shoulder straps, it keeps the shoulder cushioned and also prevents moisture from accumulating around your shoulders. It’s hydration compatible, and can securely store your trekking poles and ice axe.
