Meanwhile, here's another reference that may or may not be relevant, but shows that these words could refer to various combinations of headgear and outer garment:
"Los Chinchilpos llevan cascos rojos, máscaras negras, grueso capote, botas y pantalón de montar, lo único que los diferencia con los gamonales es que éstos utilizan casco azul."

From the picture, the "casco" here is a hard hat and the "capote" is a kind of jacket. Context urgently required: any clue could help!
Chinchilpos again: here they're "gladiators", and the "casco" is a coloured helmet and the "capote" is a long buttoned coat. The plot thickens.
