Our four-section aluminum poles are perfect for extended period treks such as long trail thru-hikes. The Denali? II consists of two collapsible components and expands from 32? to 59?. Lighter than many of the competing carbon-fiber models, ours collapse to a mere 20.5 inches for easy packing when not in use. The adjustments are rock-solid, with a push-button on the bottom section and twist-locks on top for easily collapsing or adjusting, while the long foam grip is perfect for hand position adjustments during steep traverses. Available in white with gray baskets and grips.
