The line will feature the anti-apartheid "Hand of Africa" symbol as a logo on garments marked with the number "46664."
That's the prison number given to Mandela when he arrived at South Africa's Robben Island prison in 1964.
He stayed there until 1982, and then he was housed in several prisons on the mainland until his release in 1990.
Mandela was elected president in 1994.
