For mountaineering, backpacking and trekking, poles that are strong, lightweight and easily adjusted are critical. The genius behind MSR’s Talus™ Tr-3 Trekking Poles starts with our innovative Trigger Release mechanism, which allows for on-the-fly length adjustment, letting you react quickly to the changing terrain of ascents, descents and sidehill traverses. Our SureLock™ System delivers the confidence of zero-slip performance, and a three-section shaft offers ultimate packability. Features: Trigger Release One-Handed Adjustment: One-handed, on-the-fly pole-length adjustments provide the fastest, easiest response for matching terrain. SureLock™ System: Positive-locking mechanism delivers the confidence of absolute no-slip performance. Ultralight Strength: Light, strong and reliable 7,000-series aerospace-grade aluminum construction. Ergonomic Grip: Works with a broad range of hand sizes, and ergonomic, ventilated straps deliver breathability in warm climates. Effortless Swing: Low-profile adjustment mechanism high on the pole reduces shaft weight for a uniquely effortless swing.
