Ciao, I tried a few of the large US stores and they all come up with about $50-75 shipping fees. Taxes/customs fees would be added on to that as well. There must be something you can order in Europe, maybe from ProBikeKit in the UK, or in Italy. I have a Showers Pass jacket myself, and while it is a good jacket I'm sure there are others that you can get. I buy a lot of Pearl Izumi clothes, and they are available everywhere.

If you know of someone coming over to this side maybe they can bring one back for you. I'll be going over to Milan in the next few months, but I don't really know when.
