Verified Buyer Reviewed by Mike hike from upstate NY on Thursday, October 6, 2016Compressible and warm. I am 5'6" 140lbs 39" chest and fit is good - not too trim and not too baggy. Weighs 11 oz on my digital scale. Was looking for something lighter than a classic 1 lb mid-weight and this will work.
Verified Buyer Reviewed by always1ooking4adeal from New York on Monday, June 27, 2016This is a great lightweight pullover that equals the warmth of a fleece. It is quite breathable but more windproof than regular fleece. The tailoring is really a trim fit so a large works for me (5'10" - 160lbs.) If you are any heavier you will want to size up. The sleeves are long enough for my long arms.
Verified Buyer Reviewed by Montanaskiandsail from Montana Mountians on Wednesday, March 2, 2016This jacket / shirt is made with Polar tech Alpha. with a light nylon shell. It definitely is more breathable than down or primaloft as far as I can tell.
It Is roughly comparable to a thick fleece for warmth (200 weight) but blocks the wind and light precipitation better and is thinner, lighter, and more compressible. I have worn this a lot and it just does not get clammy inside when you build up some body heat or wear under a breathable outer layer / shell like Event or Dry Q evap. I used it as a base layer in my down bag winter camping and was surprised how breathable it was.
The fit was too snug in the shoulders for me in a medium, (I am 5.10 175 lbs.) would be five stars if it had some stretch panels and possibly underarm venting or lighter arm pit fabric.
