Familiarity: I've used it once or twice and have initial impressions
I bought the S/M size as a 5'9" man and couldn't have asked for a better item to have in my kit drawer!! Wore them for the second time today on a long gravel ride in the Sierras when fall has finally fallen . I put them on under my Giordana Silverline bibs (also a great value) and they gave me a great warm ride. More than four hours worth with temperatures up and down (mostly down) all day long. Hung them to dry without washing yet so I can wear them again tomorrow. Also own the arm warmers of the same material and they just slay as layers!!
