These are Phoenix Lucra pants. They're made of tough, stretchy material, so I used to climb mountains in the snow with these, wearing gaiters except during blizzards. I've used them about 8 times in total, but there are no critical defects, and they should still be usable. I'm selling them because I've outgrown them.
