The grey rhebok (Pelea capreolus), locally known as the vaalribbok in Afrikaans, is a species of antelope native to South Africa, Lesotho, and Eswatini.

The grey rhebok is a medium-sized antelope weighing 19–30 kilograms (42–66 lb) with a long neck and narrow ears.

Only the males carry horns, which are straight, sharp, ringed at the base, and around 15–25 centimetres (5.9–9.8 in) long.

[2] Generally confined to the higher areas of Southern Africa, they typically inhabit grassy, montane habitats - for example, sourveld - usually 1,000 metres (3,300 ft) above sea level, and carry a woolly grey coat to insulate them from the cold.

[3] In 1958, Reebok founder Joseph William Foster found the name in US Webster’s New School and Office Dictionary.
