This jacket is thin, light, smooth, and waterproof. It fits close to the body so air does not cause you to become a sail on your bike. I wore this during a gran fondo in the mountains during a heavy rain day. I remained warm and my torso remained dry. I am so happy to have this jacket in my arsenal.
As a commuter, this is one of the most used fall-winter cycling pieces that has saved me in some serious Seattle rain storms. I selected the Gore Windstopper vest over a full jacket because it allows my winter weight jerseys to breathe. I can deal with damp arms that can dry out during a ride, but not with a soaked body core. The size XL in black fits over a jersey and base layer provides wind, rain, and some added reflectivity at night. I may invest in a pair of Gore cycling tights
Purchased on sale I think these are a great deal. Can't speak to durability, as I've only got 3 rides & 3 washes on them. Love the silky smooth fabric. Great pad and the straps don't move, twist, or bunch. I honestly forget I'm wearing them while on the bike. I'm at the upper end of the med size range, but they fit me perfectly. I'm 5'-9" with 33" waist, 42" chest & weigh 165 pounds. I also tried the size large which would have been fine too, but ultimately I decided I prefer the tighter fit of the mediums. Liked them well enough I bought a second pair.
I like this jacket. It's well-designed, with good material. The fabric is breathable. In coolish weather it's a winner, but as the temp warms this jacket's total lack of ventilation becomes a problem. So it's a good jacket but it would be an excellent jacket if it had pit zips andor cape ventilation on the shoulders. I still gave it 4 stars, just wish I could have gave it 5.
