The size of the helmet is originally designed for a slightly smaller head, smaller than size 60 cm. The helmet comes with two sets of pads, with which the size can be slightly adjusted. However, the inner part of the helmet can be carved, so that the helmet can accommodate a larger head!
A lamp or even a camera light holder can be attached to the rails on the sides of the helmet! The front of helmet also has an attachment point for an NVG Mount. Mounts for cameras, for example for the popular GoPro camera, are also available that can be attached to the NVG mount!
The picture shows a ACMFAST helmet. The Emerson helmet is made from a slightly different material. The NVG platform has a different design and there is more Velcro surface on the top of the head. Otherwise the helmet has the characteristics similar to the pictures.
