I bought a pair earlier this year and have used them almost every round. They were advertised as cooling as well as UV protection. I am not so sure the cooling aspect is very accurate. It may help a little but they certainly don't make me any warmer with the moisture wicking. However, the ability to avoid greasy sunscreen is a big plus. I did buy ones that were sized but were not the most expensive. They have a light elastic band at the top which helps them stay in place. It might take some getting used to but I definitely recommend them.
