When travelling in many countries in Africa it is advisable not wear or even carry any camouflage-patterned clothing.
Camouflage-patterned clothing is not permitted in many countries such as Zimbabwe, Uganda, Kenya, Gambia, Mali.
Many countries consulates advise this on their travel websites. Though in some countries travel advisories do not directly apply on camouflage clothing, it also applies to any clothing that can be construed as mimicking military-wear.
We urge you not to wear or even carry military-inspired clothing while travelling in Africa given that you may be subjected to various security checks. It is for your own good.
