Descente Thermal D-Lux Beanie Hat - Lightweight (For Women)

good alone or under another hat/hoody

I purchased this beanie to be worn under my ski helmet. I needed something on the thinner side to fit comfortably while still wearing a helmet, but also keep me warm. This fits the bill perfectly. Other beanie felt too bucky under my helmet.

to wear in the colder weather while running, seems that it will be easy to stay in position

I have an average size head and found this beanie perfect under cycling helmet. Big enough to get some coverage over ears. Excellent quality.

This is wwwwwwaaaaayyyyy too small. But I just love it, so I kept it, and I wear an ear warmer on top. It is so small (and I'm a small woman) that my ears stick out, and there's not a lot of "fitting stretch" around the base, so there's no way that it would keep your ears warm. So, it works fine with the additional head band ear warmer that keeps you ears warm and snugs up the bottom so it doesn't slip off. That said, it's really a sensational little item that does the trick of keeping your head warm. I ran in a race today in pure sleet, and winds of 27 mph with wind chill of 11. My head was plenty warm.
