From The Manufacturer

Whether you’re looking for foundational warmth, lightweight performance, or both, this Fruit of the Loom Premium Men’s Thermal Bottom certainly has you covered. Made from U.S. sourced cotton and recycled polyester, this men’s base layer has a bulk-free fitted style and is built for protection, performance, and utmost comfort when you’re active outdoors in cold to moderately cold conditions. The natural breathability of cotton offers moisture-wicking to keep you dry, and the natural stretch offers flexible comfort that does not restrict your movements. The fabric’s waffle weaves create small air pockets that hold heat next to the body, and the rib cuffs at the ankles ensure heat stays trapped as much as possible. Additional features like a plush elastic waistband, front fly opening, and flat seams prevent chafing and enhance overall comfort. This Fruit of the Loom Premium Men’s Thermal Bottom is a must-have essential for your winter wardrobe.

Expert Reviews


What reviewers liked

Made of a cotton and polyester blend, this material feels soft on skin with just enough stretch to make it great for loungewear or to be worn under other clothes. Crewneck-style top and fitted ankles and wrists help keep heat in.
If you are truly looking for the most affordable, basic option out there, this is it.
They are made with a very soft and comfortable blend of cotton and polyester, making them easy to wear under the rest of your ski gear.

What reviewers didn't like

Can run a little big in sizing and should be ordered down a size if you want a tight fit.
These won’t do a ton, but they’re great as an extra layer on a cold day.
They aren’t the warmest option around, so I wouldn’t recommend them and extremely cold ski days.
