Figure Four Tau Pack Manufactured in WA At Figure Four, we strive to create the best backpacks for your vertical endeavors; that's why our main goal is to produce the best technical fitting backpacks possible. A technical fitting backpack stabilizes the load to your body throughout all movements expected during your climb; that's something standard backpacking packs and many climbing packs fail to achieve as the terrain becomes more vertical. Not only does our technical fit make our packs more comfortable, but it improves your efficiency by reducing the energy required to stabilize the load and allowing the pack to move with you. Minor shifts to stabilize the pack load throughout a long push add up.

Our designs blend creativity with a touch of minimalism, rounding out a light-technical fitting pack with features geared for climbing. Our materials and packs are tested excessively in the vertical environment, resulting in durable packs with well developed features.

We think and obsess about our packs so you don't have to. Check them out below:
