The sleeves look good. Probably won’t use them until next summer. In New England, where I ride, the sun is now less intense. Although I might use them as warmers on intermediate cool/warm rides.
Very soft and feels great
Work well! You will get a bit sweaty -- you are wearing a garment, after all -- but you will not be sunburnt and you will be cooled well by the breeze. Excellent for long, sunny days in the saddle.
Awesome. I found the arm covers a much needed relief from otherwise being sunburnt.
