jensen_meg944496wrote a review of Castelli Sottile Jacket on May 11, 2012
Lightweight and packable (much moreso than my Pearl Izumi WXB Barrier rain jacket) and it does shed light rain (I have yet to use it in heavy rain). The fit around the body is nice and snug but I found the sleeves to be very big and loose on me so it does flap in the wind quite a bit. I also find that when I am pushing hard, I get soaking wet under the jacket so I was a bit disappointed in the breathability, although I'd suspect it is more breathable than some other rain jackets out there. Price is a bit steep in my opinion.
