RVCA (pronounced: rue-cah) is a clothing company based in Costa Mesa, California. The logotype for RVCA portrays the letter A without a crossbar. This leaves it looking like a lambda .The 'V' looking character in RVCA name is a 'U'. The 'U' is written in traditional Roman script, and thus appears as a 'V'.
Occasionally, RVCA is written in a different script or appears in art where it is clear that the true name is 'Ruca'. 'Ruca' can be translated as clothes in Greek, and it is believed the 'V' as 'U' convention arises from this Greco-Roman connection.
