Neutral colours — khaki, olive, grey, sand. Dark blue and black are worth avoiding because they are known to attract tsetse fly, which bites hard and is present in parts of the northern circuit.
Do not bring camouflage clothing. Camouflage is restricted to military use in Tanzania and civilians, including visitors, can have it confiscated. This catches people out every year.
Layers matter more than any single garment: a fleece or light down layer for the first hour of a morning drive, long sleeves and long trousers for sun and insects during the day, and something warm again in the evening — especially on the Ngorongoro rim, which is high and cold at any time of year.
