I’m 5’8”, 165 lbs, 41” chest and I bought this in a size 52. -This jacket vents massive amounts of air; so much so that with the Gore-tex liner removed and every vent closed it still flows a noticeable amount of air. -Extremely comfortable and lightweight when worn; after a quick break-in the articulated elbows, light weight and soft outer material make it feel more like a sweatshirt than a stiff protective jacket. -Slim fit; I would consider going up a size if you plan on layering anything underneath the jacket besides the Gore-tex liner to use it in colder environments. I can’t even fit a micro fleece under the size 52 jacket. I bought it primarily as a summer jacket with the intention of wearing a synthetic t-shirt under it with no liner so for this purpose it’s solid. -The collar on this jacket is the only thing I think could be improved. It is a tall collar for use with the BNS and has a snap on the back that lets you snap it down. It is difficult to get comfortable around the neck and it’s a tight fit. I have a 16 inch neck. When it's warm it has a snap to keep it open and flowing air around your neck which is great but the exposed Velcro patch sticks to the bottom of your helmet. There is a plastic attachment point on the left side of the collar for the BNS that gets in the way if you wear a pack or hydration bladder. -The zip-on/off sleeves do not form a complete seal to the jacket. Even with the zipper completely zipped there is still about a 1.5 inch gap under the arm pits. This is excellent for warm weather but causes noticeable drafts when the temp drops. -For the price it should come with a removable CE back protector and not a cheap foam pad. User could then decide what kind of protector to wear based on conditions and type of riding.
I bought it as a non Gore-tex jacket to get me from the house to the trail. For this purpose it works very well and I am very happy with it. I don’t use the inner liner so I don’t know how it does in the rain. During warmer weather the vents work very well and you can effectively manage how much air moves through the jacket. For me I think it strikes an excellent balance of off-road user adjustability and touring capability to get you to and from the trail. I don’t think this is a high country all season jacket unless you go up a size. Overall it’s light, comfortable, and moves with you while you’re getting after it.
