Familiarity: I've put it through the wringer
Extremely nice looking jacket, very pro fit the collar on this thing is heaven. Let me begin with by saying I have a huge furnace and sweat an insane amount during intense workouts, so breathability is very important to me. I have worn this in 23 degrees with light weight base layer and it's been plenty warm, almost too warm. I've also worn this on 40 degree days, it's a little too warm at that temp. I do find that I need to unzip to let some heat out more frequently than I would like. Wind does not get through this jacket in the front or the sleeves I have worn this without base layers and have not gotten cold. Most of my rides have been road rides this fall / winter around 90 min and this jacket sheds water, wind, snow and anything you can toss at it. I only wish it was a little more breathable, but again it could be me and my temperature range because I can overheat very easily. I am 6' 180 lbs and wear an XL this fits racer tight with not a lot of movement in it, sometimes find it difficult to get stuff out of the pockets because it's tight on my shoulders.
