On this page you will find a wide selection of soft and comfortable woolen underpants for men. Our selection offers trunks with or without a fly that are made from organic merino wool as well as long underpants made from exclusive merino wool. Woolen underpants are suitable as an isolating layer to be worn close to the skin. Due to the temperature-regulating properties of the merino wool, woolen underpants can help protect against cold weather as well as against over-heating. They can as such be worn all year.
