Here are some genera 1st thoughts on the SKRE Hardscrabble Jacket, I have only had the opportunity to wear it outside the house & at work. But for what it worth, as noted by the manufacture, the jacket runs on the small side, I bought an XL which fits my 6'1 180lb frame just fine, whereas I would normally wear a size large. Second thought is that (for me) this jacket seems to provides less warmth than I would expect for the thickness of the material, but that may be a plus for on the go style hunting. The jacket seems to be well made & has nice pit zips & chest vents, so it should breathe real well, if that what you need. But time will tell how it fits into my clothing system.
