Are these the thicker sun sleves for warmth or thinner for cooling? I want cooler. My arm length is 17 1/2 inches. What size should I get?

Asked by: Qball
​These sleeves are intended to help wick moisture away and keep you cool with the vented panels; for an arm length of 17.5 inches we recommend a size Medium.
