Ryanwrote a review of Marmot Cruz Convertible Pant - Men's on May 10, 2013
I own three pair of these pants! Very flexible and breathable. I'm 5'7 and about 165-170lbs and use the 32" waist in the short version.
Water repelling will repel dew or anything similar. If it's a heavy downpour you can expect your legs to get wet. However, it doesn't take to long for these pants to dry. I typically just hang them up at night and they are ready to go in the morning.
