These are the Gen3 Non-metallic Night Shifts made from Carbon Fiber infused polymer material. They are extremely strong and have a more refined finish than the Gen 1 &2. We put these through lots of break testing to make sure they could handle serious impact. See below for the dimensions of the finger stalls. **These models have a Glow In The Dark web logo!
