This version 2 of our helmet that is screen accurate. It is a professionally cast fiberglass helmet. It's made of a 2 layers ofof fiberglass and can take the abuse of trooping. The front sensors can accommodate LEDs. Note that there is a huge difference in the durability between a 3D printed helmet and a fiberglass helmet. These helmets are first rotocast with resin for high detail and then a layer of fiberglass is added to the interior for durability.
