I have to tell you, I absolutely love Gore Bike Wear stuff! My brother bought me some winter tights this year. After trying them on, I didn't think I would like them because the chamois felt bulky. However, AFTER I rode with them, I have to tell you, THIS IS THE BEST bike garment I own. The chamois turned out to be very comfortable.
I ride year round. I've ridden in snow, rain, sleet and sunshine. I've used a lot of different brands too including: Castelli, Novara, Pearl Izumi, Specialized, Louis Garneau, Hincapie, Sugoi, REI and many other brands and I have to say i like my Gore stuff better than any other brand.
I must confess though, the model I have isn't this same one as this one but the other Gore Bike Wear stuff is absolutely amazing. I own mountain bike shorts, jackets, and jerseys from Gore and they are really, really good stuff.
