For work in hot areas you need drinking water to hinder dehydration.
Our suits can be equipped with a fix mounted rucksack at the back of the suit for a 3 litre NBC resistant drinking - water bag. This bag is permanently connected to the mask by a drinking hose.
The main feature is, that no additional bag and carrying harness is needed (standard carrying systems cannot be decontaminated).
Additional the water bag can be equipped with an isolation bag to reduce the heating of the water from the sun.
