Unless you're fixin' to borrow my hat [which wasn't happening] you need something with a wide brim that will keep you shaded.

[McCree gently plunks that beautiful sombrero on 76's head and smiles pleasantly.] See? Looks and fits fine on you.

[It looks hideous. That pleasant smile is just barely masking a laugh.]

Or show me somethin' more preferable that meets your very dignified standards.
