The immense popularity of their underwear is due to their heavy focus on unique designs and the emphasis they put into creating the most comfortable fit possible. SLY brings young designers on board and partners with local artists to help create new prints and styles. These quirky and youthful prints are then mixed with comfortable cuts and feel-good fabrics. The result is stylish yet practical underwear for both men and women.
