I have this jacket, got it on an Outdoor Research black friday special. I packed it as an emergency jacket, on a trip to the California coast and ended up needing it. With just a t-shirt underneath it kept me just right at not shivering at night at about 40 degrees. I did get hot during the day in the low 50s. I'm 5'8" and 180lbs (kinda chunky, im about 15lbs over my in shape weight) , it fits snug, but I still have a few inches of room, more than some of OR's technical jackets. I have 32" sleeves in dress shirts and I bet these are 34".
It packs pretty small, like a half loaf of bread. Everyone asks where I got it from and likes it.
I think at this price it's a good deal. I paid $185 for it on black friday sale.
