Johnny Heusser, Head of R&D, über Innovation bei optrel.
“Black crystal and the swiss air. optrel' s brand new mask and PAPR. I don't have to talk about the crystal helmet. The fact that I own 3 already PAPR and non PAPR speaks for itself. Words can't describe how lightweight and comfortable the new PAPR system is.” Thomas Gollosis (@thomasgollosis)
