A protective garment including a suit (2) for encapsulating substantially the whole of a wearer's body has an air conditioning unit (8) including a fan (10), a power pack (14) and a water vapour absorbent/adsorbent element in the form of a canister (12), and optionally a filter (16). An air path selector comprising a multi-way valve (20) is provided and allows a wearer to alter the air path within microclimate of the suit. In one operational mode, the air path follows an open circuit from the external environment through the filter, circulating within the microclimate and exhausting to the environment. In another operational mode, the microclimate is isolated from the external environment and the air path is a closed circuit, the air passing through the canister. |
