Good multipurpose skull cap.
I actually purchased this because it was the more affordable skull cap I could find compared to the likes of Arcteryx and Patagonia and such. I have used it for general dome insulation and also ran a few chilly trail runs and 1 race in this hat and it has provided ideal insulation for running in cold weather, well cold for New Mexico. It is definitely a skull cap and you don't really get full coverage over the ears, so be aware if you're looking for a full on winter hat. Cheers.
