Embarrassing gear-wh0re confession time:

I own both the red Goretex jacket and the mango Shower's Pass. I love both of them to death. The Red Goretex jacket has no pitzips and doesn't breath as well, but it is fabulous for very cold wet riding or serious torrential rain it is the only thing that will keep me truly dry. For all other rainy conditions from medium-cold to just cool to mild/warmish temperatures, the Shower's Pass jacket is the best. The pit zips are smallish but the huge back vent makes a big diff. Also, that eVent fabric is nice.
