Great convertible hiking pants for women who need shorts that zip-off at knee length - Prana Monarch Convertible Pant - Women's

I need pants that zip-off at knee-length. These are the ONLY convertible hiking pants I've found that zip off long enough to cover my knee. I currently own three pairs of these and have put them through the wringer. I've hiked 100's of miles in them and absolutely love them. I do think the sizing runs a bit big. I'm 5'3" and weigh 115 lbs. I bought the Size 0 and it's still a bit big, but can be accommodated by the drawstring in the waistband. LOVE these hiking pants.
