I am an environmental scientist and explorer who spends a bit of my time working in remote, fairly extreme environments. I was initially skeptical about taking this fabric into the back country so I eased into what I used them for. I've had them for just under a year, but they've been with me for two expeditions to the Peruvian Andes, a trip into the Amazon basin, hiking around Hawaii's Mauna Kea volcano looking for a rare bird, and a few trips into the Colorado Rockies. The fabric is impressive. Though they are 72% cotton, they do dry very quickly and they are tough as nails - they show very little wear despite a year of abuse. They're fairly comfortable in warm weather too. Also, the fabric doesn't stretch out much when wet, which is a failing of many nylon fabrics.
In short, unless I know that I'm getting heavy precip in cold conditions, these have become my go to hiking pants.
The only reason they don't get 5 stars from me is that, for hiking pants, the cuffs are cut a bit narrow, which makes them look a little awkward for high-cut hiking boots; however, the cut of the cuffs make them look better with low top boots and better for rock climbing as well. If I destroy these tomorrow, I would immediately order another pair. Great job MK!
