Critter wrote a review of prAna Stretch Zion Convertible Pant - Men's on January 18, 2012
The zipper to remove the leg sits right at my knee and doesn't stretch like the rest of the pant. I find this constricts my movement a bit when climbing. Its also a bit scratchy around the seam where that zipper is as well. Other than that they look good, breath well, and fit pretty true to size. I usually buy pants with a 32" inseam and didn't find these too long like other reviewers.
