I actually bought this jacket as a commuter Summer biking jacket to protect from the sun while still being able to wear my normal work clothes (thus the reason to opt-out of a sun hoody). So far, biking in 90 degree (dry) weather with this jacket has been quite comfortable. In my use, it breathes very well and provides ample coverage to protect from the sun. The fact that its highly stowable is a big plus. I took my regular size (not preferring a slim, athletic fit) which fits perfectly as it leaves enough room for airflow without looking sloppy. My only bit of feedback would be to add a minimal drawstring to the waist to be able to dial in the wind protection when the weather changes to be a little cooler in the evenings

I have the blue version and it is very light, it breathes well, the spf protection was major for me because at the top of the mountain sun hits much harder. Overall this jacket is a must and i recommend pairing it with the konseal pants for total sun protection. 10/10
