I used these for the first time for the first significant dump California has seen in 2007....and some of the wettest snow I've ever seen. No water got through, not even a drop. My gloves were thoroughly soaked but my legs were as dry as a bone. Light, warm and generally fantastic pants.

I bought an Arc’teryx hardshell jacket and was pleased with the performance of the coat. The Arc’teryx hardshell pants share many of the jacket's performance qualities. The pants are very light and shed wind and moisture well. The construction and fit and finish of the pants are excellent. The suspenders work well and offer ample adjustment. I live in Colorado and wear these year round. Breathability is more important to me than water resistance. The Arc’teryx pants are very breathable. Zippers move easily. Occasionally, I wear crampons and the fabric on the inside of the leg of the pants did not rip when scraped by the teeth. My only complaint is the pants lack a rear pocket for my wallet.

These pants are great. Straightforward, and the full zips were great when I got too hot or needed to pull them on over my crampons and boots.
