Review on Men'S Fleece-Lined Thermal Underwear Set With Open Fly Design - Long Johns Base Layer Top & Bottoms by Brandon Grzankowski

This thermal underwear set helped me get through the winter in the southeast part of the United States.

I definitely felt warmer than when I didn't have this base layer. However, it probably won't be warm enough of a base layer for some colder climate zones or if you're outdoors a lot in the bitter cold.
