I have been a big fan of gortex over the years, coming from a backround of marathon speedskating and ultra running. It sure saved my boney frame in many sub zero competitons. Now into long distance cycling the benifits of this material is worth every hard earned cent. I especially like the gore panels on my bike tights.....wind shield factor goodbye. Another factor with this amazing material is it's durablity. I'm wearing some 15+yr old jackets that are still in good shape. I say go for it if you have the extra bucks.
