I use a Salsa Cycles jacket made of clear PVC vinyl w/velcro and breathable mesh. I had to use it once on the way home and it was okay. It got the job done and was comfortable. Kept me from being a soaken mess but I would like to find some "chaps" to match the jacket and keep my pants from getting soaked, too. I carry it in my messenger bag at all times while commuting (and in my saddle bag for club tours), rolled up tightly to save space. It is very nice to have and seems well made but at $25 at the LBS it was not cheap. I use the X-large size since my arms are so long and I want to get the proper "coverage".
