Duofold Men's Orginal Union Suit

Great, comfortable, warm.

Been wearing union suits for 20 years, different brands, different styles. Doufold is top notch, wicks sweat away if you get too warm, keeps you the warmest in the cold.

Unionsuits have become so comfortable to me i have different styles so i can wear them all year, thick, thin, long sleeve short sleeve, thin sleeveless with short legs like boxer shorts to wear with shorts and sport shirt.

Go on, try them. in time it will be the only underwear you wear too.
