Just took a trip out to Colorado and rode Vail, Breck and Keystone. Weather was chilly but warm on some days and all I had to do was shed my under layer and I was good to go. I’m 5’11” and weigh 205 so I got an XL and it fits great. Loose enough to get good winds and air flow. Great fit.
Very breathable but an awesome windbreaker, perfect for chill spring days on the mountain. 5/5!
