These are Mammut SOFtech TREKKERS Pants. They're a bit thick, so perhaps suitable for fall and winter. There's some dirt near the hem that didn't come out with regular washing. It might come off with soaking or scrubbing with a brush, but I'm hesitant to do that for fear of damaging them, so please be aware of that. Otherwise, the condition is quite good, I think. I believe I bought them last winter, but I'm a little unsure. I've probably worn them about 10 times, but I'm sorry, I'm also vague on that.
