Bailey S.wrote a review of Black Diamond Compactor Backcountry Ski Pole on December 27, 2016
Familiarity: I've used it several times
Funny to read another review about skiing with a tree limb in hand. These break easily or me (with odd failure modes). They also jostle at the connections, which I guess is to prevent from freezing. I would probably pass up. They do compact VERY nicely, like very few other poles.
Also have to say the Black Diamond service and warranty folks are absolutely amazing. Great company.
