A couple centimeters of adjustment can make a world of difference when you're skiing deep snow, steep lines, or a combination of the two. The Speed Lock 2 mechanism lets you make quick adjustments on the skin track if needed, and the grip extends down the pole so you can choke down on short, steep sections. Like most Leki poles, the Aergonlite 2 Vertical features a strap that will detach under pressure, like from an avalanche for instance, and there's a trigger that removes the strap if you'd rather not ride with one at all.
