A cap comprises a crown sized to fit on a wearer's head and a visor. The cap includes a track mounted to the crown and a slide member to which said visor is mounted. The visor can be removably mounted in the slide member to allow for changing the cap's visor. The slide member can move axially along the track, to allow for selective positioning of the visor on the cap. Additionally, the slide member can be an articulated slide member which allows for altering the relative angular position of the visor relative to the crown.
