Black Diamond says:
Our durable, four-season, carbon trekking pole now has improved joint support and increased durability, making the Alpine Carbon Z-Pole a strong yet ultralight pole for mountain missions.
Z-Pole Rapid Deployment System
Speed Cone technology comes from our expertise in avalanche probe design-a key component of Z-Poles' stiffness and fast deployment. Simply grab the grip and the first shaft section, and pull them away from each other. The pole will snap into place and lock. Each Speed Cone guides a shaft section into place, and stiffens the joint when the pole is locked. Protective, flexible tube ends cover the pole’s Kevlar center cord when folded.
