Ohio Kayakerwrote a review of Immersion Research Arbolito Pant - Men's on December 10, 2010
I bought these on Steep and Cheap and wish I bought them all out. They are without a doubt the most durable pants I have, and they are comfortable too. I use mine while working in the crawlspace under a house. I've never had rocks penetrate the almost burlap thickness of these pants. They aren't lightweight, so maybe not you're typical synthetic hiking pants, but they will last 10 times as long!
