I got my first R1 about 6 or 7 years ago and and have used it a ton. Freaking love it. It doesn't fit that great though, pretty boxy cut. I had to size up the XL because I am tall (75in) and lanky (185lbs). The large was far too short in the body and the arms. I am used to wearing stuff like a walking hanger anyway. At any rate, I finally got a new R1 over the holidays and in addition to having a much slimmer cut, they have made some significant changes to the jacket since I first got one.
The XL 2008 (not sure) version weighs exactly the same amount as the Large 2014 version, down to the gram:


The sleeves are significantly different, added thumb loops and different material, but the biggest difference is the depth and puffiness of the grid fabric. Keep in mind that I have washed the jacket on the right like 50 times maybe:



Also. the chest pocket is significantly smaller, maybe due to the cut being so much slimmer:

I really like the fit better, but I am thinking that the old fabric makes for a warmer jacket.
