These are amazing. I put quite a bit of time into researching these pants, and I could not be more happy with having them. On top of being comfortable and durable for two solid seasons of use so far, I had a particularly impressive experience with these pants last weekend. While glissading, I punctured a small pencil tip sized hole in the thigh of these pants. The hole was barley noticing, but when I finished my trip I noticed that I had in fact sustained a pretty significant gash in my leg. The tiny hole in the fabric hid the fact that the ax had broke skin. The lack of a significant tear in these pants is incridible. I will recommend these pants to anyone I climb with.
