It took me a little while to figure out and really love the Storm Racer. It's now one of my favorite jackets, and if it's nasty enough for this to come out of the closet it's sure to be a good adventure. I'm a wannabe product tester for Patagonia, so when I received this sample last spring I started going for road rides wearing it anytime I could catch a good rain storm. After a few rides I started to appreciate how sweet it is, and realized that it's really just a Houdini, made out of super lightweight 3 layer fabric. It's seam taped, and fully waterproof, while still having the same self stuffing feature of the regular Houdini. I had a chance to head to BC to ride for a week at the end of the summer, and this jacket was at the top of my packing list. I spent several days riding in it all day, and it worked incredibly well. Very breathable for a waterproof jacket, with a great fit on the bike as well. Can't really say enough good things about it, or how much I like riding in it.
