This hat is very thin, but don't think of that as a bad thing.
I used to run in a Ron Hill thermal headband, but always took it off as it was too warm after 5 minutes. This is thick enough to retain heat, but not too thick that it become over hot on a run. This morning it was 7 degrees and it became too hot after 15 minutes or so. Despite it's thinness, it does a great job. I'm going to invest in the headband version too for those kind of days otherwise sweat pores into my eyes.
I use it for under my bicycle helmet keeps head and ears warn
Purchased this product to keep my head warm in winter as I have very little hair to protect me on the cold morning runs
good value does its job nice and light
