ClimateRight by Cuddl Duds Women’s Mild Essential Base Layer Livaeco Jersey Long Sleeve Crewneck Thermal Top, Sizes XS-4X

This is such a great find. It's so important for me to have a good base layer in cold weather because I get cold so easily and retaining body heat is key. But thermals are too hot. Thanks just right. It's lightweight and doesn't get too hot but doesn't help retain the heat. The size was a little big. I usually wear size XL and I could be downsized and if you are using as a base layer I would.

This black, thin, long sleeve crew shirt by cuddle duds is really comfortable. It's not very thick so it's for days that aren't too cold. I really like the thumb cut out at the bottom of the sleeve. It's not super tight, which I prefer and appreciate. I usually wear a small or medium, and I got the medium. I could have gotten away with the small though.
