The Runderwear™ Men's Multisport Briefs are designed to provide exceptional fit, feel and support during your run. Our award-winning underwear will keep you chafe-free - guaranteed. Constructed using 360° seamless technology, which means there are no side seams or tags, resulting in less irritation against your skin. Carefully positioned micro-perforations make the fabric breathable, optimising airflow and core temperature control. Lightweight, technical fabric is moisture-wicking and removes sweat quickly from your skin to keep you dry.

This version of our Men's Running Briefs also has a pouch built-in to the front to store a protective box, making them perfect for running or any other sport that you need protection for where it matters most!

Men's running briefs

An excellent purchase. very comfortable even for long runs.

Great to hear that you are loving the Runderwear Briefs and they are providing you with the comfort that you had hoped for! Happy Running.

Comfortable and no chafing :-)

I bought these as normal boxers were giving chafing issues. Runderwear is not sexy, but very comfortable and supportive. Best underpants for running i've ever owned.
