Don’t waste your time with adjustable length poles. They sound good in theory. In reality the adjustment mechanisms always break, they add unnecessary weight and from my perspective there’s little value in having a pole that can collapse to a shorter length. Instead, get a solid carbon fiber pole, that’s not designed for ultralight applications. Accept a little extra weight for bombproof durability. I hunt sheep and moose every year and have been ski touring/mountaineering for over 20 years. Over the years I’ve used, or seen in use, many different poles. From my perspective, all adjustable poles have been junk. For hunting in demanding terrain, carrying heavy loads and relying on poles for support......a person needs a solid fixed length pole. Adjustable poles are for casual users.
