PinkPilot..the jacket was thrown into the wash with all the other gear from the day and the week..and came out without any problems. Came out fresh and clean looking. After being caught in the rain, and not being sure about how well my back would stay dry, I still can't say enough about this jacket. I am thinking that maybe that back black panel, with the heat from my body passing thru there, maybe that's what kept me dry..burning off all that moisture. I am not sure..all I know is that I wasn't expecting it and it worked for me. My cell phone had stayed dry in the little chest pocket. Yes it is a pricey garment, but I can't say enough about this jacket/jersey. Maybe I should email cannondale themselves..but I am sure they already know or they wouldn't have designed the jacket
