I've run the corrugate guide jacket and pant this year. Pants have been bullet proof so far, through turkey, many hikes, bear, early archery and now a Utah rifle hunt. The jacket is thin, it will not keep you warm or dry. It does block the wind fairly well. I run a wick hoody and a Kalmath hoody underneath if i need it, and have been comfortable down to 30 and pretty steady winds in Utah. IMO, the jacket is good for blocking wind, or protecting more fragile base layers or down jackets, but it is not built to keep you warm or dry. Overall I have been happy with it, but have also kept my expectations realistic.
I'm 5'11" and 170 and run the Large. I originally got the medium and the size was good, but it was too short through the torso. I have some extra room in the large, but the length was much better.
