I bought these for my husband for running. He likes that they aren't bulky but protect his hands in cooler weather but hasn't had the chance to try them in COLD weather (sub-29-degrees). They are not quite large enough and don't stretch well, but they are not worth the hassle of returning. My huband is 6'3" and has the x-large, so there isn't an option for him to size-up. BUT, they are easily stashed in a pocket of his running jacket to have for his runs, which is important to him.
