Product Review; "These Thermal Underwear are very insulating and surprisingly comfortable - like a nicely fitting pair of pajamas. Worn under your normal pants even a freezing windy day will be tolerable, I'm so proud to say WSI Sportswear makes 100% of their clothing in the USA, as so many other Winter Weather Gear Manufacturers have moved assembly overseas. I got mine on discount, so stay updated to the deals but either way they're worth every penny!"
