Nice jacket, not for race day thoughI was really impressed with this jacket when it arrived, and it's very comfortable to ride in. I bought the clear one so that my jersey would still be visible underneath.
The sleeves are a nice length and have just the right tightness of elastic around them for a comfortable fit around the wrist. The fabric is really nice, and because of it's unique stretch it doesn't make rustling noises while you're riding! It packs up fairly small, it will fit in a jersey pocket but I usually put it in my saddle bag, and it's great for putting on when you ride into a surprise shower.
The jacket is not very breathable though, and I find if I cycle in it for any real length of time quite a lot of moisture builds up on the inside. This isn't a huge problem, and it's not something I've ever noticed while I was wearing it, only once I've taken it off.
I'd definitely recommend the jacket, just not for race day, or if you were anticipating cycling in the rain for a while.
