Viewfinder for DYE i4 / i5 masks - Smoke Fire
With the interchangeable viewfinders in the DYE I4 and I5 mask system, we can adapt our mask to the current conditions or simply replace a worn out viewfinder.
The visor on offer uses Thermal Lens technology, i.e. it has two layers which prevents evaporation and provides excellent visibility even in the worst conditions.
