Just took these on a 8 day trip in the Boundary Water Canoe Area in northern MN. These things rocked. I used these all day, every day. Only complaint, if you can call it that, was that the DWR started to fail after it was completely covered in soot/dirt/crap. I'm washing them right now and hopefully the water repellent will come back. Lightweight, convertible (zippers didn't bother knees at all), durable, dry quickly.
I'm 5'8" 140 and ordered a small/reg. Waist was a good fit but the inseam was long. Had my mom (skilled sewer) tailor them up to fit. Probably should have ordered a small/short.
