James E.wrote a review of prAna Stretch Zion Convertible Pant - Men's on March 1, 2012
I bought these because I was tired of my friends calling me names in the climbing gym for always wearing my Nemesis Knickers. They still call me names. Pants are Prana, so they're bomber, what would you expect? Zipper doesn't get in the way of movement climbing unless you're Chris Sharma, which you're not, and if you get too hot you won't have to impress the ladies with some white upper-thigh because the shorts are a bit longer than the other North Face / Patagonia variety. I wear these for pretty much every activity I do that falls in line with being outdoors in mild temps, and I even can pull them off in the cubicle at work (though this is not recommended if your boss is a douche). I'm 5'11, 160, and I went with a medium. They fit fine.
