That jacket (and most of the concurve/gore bike wear product line) are made from gore windstopper. It's intended to stop wind (does this very well). It breathes better than goretex. It is not waterproof like goretex but it will keep you dry in very light rain (then again so will other fabrics). Gore doesn't claim windstopper is waterproof (only the performance ad copy people make those claims). Windstopper is a good choice for biking in dry cold weather.

I owned that jacket for a while. I liked it but it was a bit snug around the shoulders/pits so i returned it (they need to compensate for that zipper).

Re. hoods. On some jackets, the hood tends to stay immobile when you turn your head sharply, especially if the hood is not cinched down around your face, and you end up looking at a hood seam, instead of, say, oncoming traffic. The more rigid the material (like 3 layer goretex) the more likely to have this problem. Helmet covers don't have this shortcoming.

Its hard to find a good bike jacket.
