Bellwether Aqua-no. I love this jacket!! Pit zips, back vents, very breathable fabric and totally windproof. I've worn this jacket with just a short sleeved jersey in 50-60 degree temps and have been very comfortable. I've also worn it with several wicking layers in 13 degree/20mph wind and I was toasty warm. Can be found for 80 bucks or so.
