Riding in temps below 50 degrees. They shed light rain and try quickly. They have changed the design with the same fleece used throughout the leg warmer. In the past they had a lighter material that allowed for more freedom of movement.
Wonderful knee warmer
Used to love these, and had two previous versions. The 3g ones are much shorter with large ankle openings. No go for me.
Castelli tends to run small, I sized up and fit was good, zipper at ankle was nice and seemed durable. Keep me warm in 50 degrees farenheit range.
