This has brain: Raptor Tactical Sentinel Skull Crusher

We all want to wear a night vision device (NVG), but not necessarily always a helmet. In order to make the attachment a bit easier and airier, so-called "Skull Crushers" have been developed. A new model has now been released by Raptor Tactical, which looks very promising. Advantage: All common NVG shrouds can be attached. HERE is where you can get the Sentinel Skull Crusher.We particularly liked the thoughtful details such as cable channels and the ability to attach Picantiny rails. Hopefully, this Skull Crusher will soon be available in Europe. Until then, here is a video from the manufacturer, which shows everything very well:
