Sin Salida (2015) (Spanish for "No Escape"/"No Exit") was a major professional wrestling event produced by the Mexican Lucha Libre-promotion Consejo Mundial de Lucha Libre (CMLL) that took place on Friday night July 17, 2015, in CMLL's main venue, Arena México, nicknamed "the cathedral of Lucha Libre" in lieu of CMLL's normally scheduled Super Viernes ("Super Friday") show. The main event was a best two-out-of-three falls Lucha de Apuestas, or bet match where both Rey Escorpión and Último Guerrero "bet" their hair on the outcome of the match and the loser was forced to have all his hair shaved off afterwards as per Lucha Libre traditions. The show also hosted two first-round matches of CMLL's 2015 En Busca de un Ídolo ("In Search of an Idol") tournament where Esfinge wrestled Canelo Casas
