Easily the best vest/gilet I've ever purchased. Fits great, looks even better. Typically wear a medium, medium fit exactly as should be.
Fits true to size, nice materials, my only thing is I wish the zippers were nicer quality (they feel a little cheap and I personally would have paid a few dollars more to have nice zippers)
Felt awesome. did use this on a 64 mile bike ride recently. I had to leave early at 5:30am and needed an extra layer to face the early morning chill. I got back around 10am when the temperature had gone up to 90 F. (Los Angeles, CA) It still felt comfortable at that point.
