Fyn was born from the idea of replacing uncomfortable mesh liners with a quick-dry FYN brief - designed "for your nuts" is what our customers like to say. You can say goodbye to wearing uncomfortable trunks. Every detail of the Fyn trunk, from the fabrics to the zipper pockets have been carefully thought out to be the most comfortable, functional, high quality and stylish trunks on the market. What started off as a more comfortable swim trunk has evolved into an every day short that guys are rocking all summer long.
