Donald L.wrote a review of Arc'teryx Proton AR Hooded Insulated Jacket - Men's on November 15, 2017
Familiarity: I've put it through the wringer
Fit: True to size
Very Solid Jacket for Mountain Alpine Cold Weather, great protection in the chest, arms are well insulated very flexible even when adding a shell. I use it with a Beta AR Shell and they are great together just enough room in the Proton for myself 5'11 200 lbs. says semi fitted does not seem like it because it fits my older not fitted body. I would recommend and it will be durable not really meant for a around town layer it like abrasion!
