Grivel Grivel Trail
A trekking pole that's easy to adjust on the fly.
Model: Grivel Trail
I rarely bother to change my pole length while hiking, because I find even the simplest locking mechanisms too fiddly—but the SureLock eases on-the-fly adjustments. A unique trigger system lets you adjust this three-section aluminum pole with one hand: Holding and squeezing the handle like a syringe releases the lock and allows you to push (or pull) on the middle segment to adjust the length in five-centimeter increments. The collapsible bottom segment locks into one fixed length with a push-button mechanism. Dings: The relatively heavy swing weight gave it a sluggish feel when I was skiing downhill and the plastic grip gets slippery with sweat or rain.
