After two years of use, I am pleased to say that these pants are very durable. They barely look any different from the day I bought them, and I've used them for countless days. I normally wear them with gaiters for: ice climbing (to protect them from crampon punctures), backcountry nordic skiing (in powder conditions), and winter camping/hiking/snowshowing (in powder conditions). When AT skiing, the mini-gaiter is snug enough around my ski boot so gaiters are unnecessary. Using a harness with these pants poses no problems. In all activities, the pants seem to stand up to whatever demands I impose on them.
Cons: Waist belt not tight enough, no lace hook on the mini-gaiter
