These worked perfectly! They aren’t the warmest but do the job for long cold runs in Texas. I ran a half marathon in 40 degree weather with these on and they kept me warm. They are a bit smaller in size, similar to what other reviewers have said. But I’m a small woman with small hands so the size medium I ordered were perfect. They were warm enough that I took them off at about mile 6. So overall, I’d definitely recommend for a light coverage, snug fit, glove.
