Took these on a 6.5 mile "test hike" on the Black Mountain Trail, in the extreme heat of the Nevada desert in August, on an uncharacterisically-humid day. I used them as shorts and the parts of my body covered by these stayed dry and relatively cool; they even fit so as to prevent chafing. I have not had a chance to try them in cold or wet conditions, but I spilled water on them and the water beaded up nicely. I ordered a size slightly larger than my usual fit, to account for an athletic physique/round derriere; these fit very well, except for being a bit large in the waist area. Having an hourglass figure and very narrow waist,I can't fault the pants for this. They are fairly flattering for a hiking pant. The only thing I found disappointing is that the zip-off pant-legs don't also have a vertical zipper for easier removal when wearing shoes/boots. Highly recommend!
