The Eco version of the FAST helmet is externally identical to the more expensive version and therefore has an NVG mount (for attaching a night vision device or an action camera) and two ARC rails (4 Position Accessory Rail Connectors; for mounting all kinds of tactical accessories). However, unlike the more expensive version, it is padded slightly differently, is not equipped with an Occ-Dial liner kit and has a different attachment strap. The comfort is therefore somewhat lower and the adjustment options are limited. The helmet also comes without accessories. For this price, however, you get a lot and the helmet is also very suitable for SOF reenactments. This helmet is made of synthetic material, it does not have any ballistic protection!
