I've dropped some weight (20lbs) after a back injury and medical issue that's left my 36 tall traverse and mountain pants feeling pretty loose. I'm looking at some mesa and grindstone pants in possibly a 35 or 34. I've been reading recent reviews that say they might run small and a bunch saying true to size. That makes me wonder if there are some quality control issues across the line or if there are significant size difference from pant to pant. What is your experience with Sitka and their sizing?
