I really like this jacket! I’m 6’2”tall 42” chest 32” waist 165lbs. 14” biceps the first day I wore this jacket it was 48 degrees with a slight drizzle I wore a long sleeve thermal jersey underneath and was very comfortable on my ride and stayed dry. I still had a little room for more layers and the sleeves were a little loose but not baggy or flapping. It’s not an aero fit, but just a little loose The waterproof strip on the back kept the tire spray form soaking me, big benefit, and with the drizzle it kept me dry. Wouldn’t wear in a steady rain though The front seemed a tad short for my height but in the saddle it felt good and had enough length in the back . For those who are interested in a super light weight jacket, it gets the job done! I found that the size chart for this item was true!
