So what is ODS,? Well first of,f it stands for Omni-Directional Suspension and to explain it as simply as I can, it is like adding tiny shock absorbers between your noggin and the ground, or whatever your dome is being threatened by. In the standard helmets that we all have been running our entire lives, the helmet is a molded EPS liner and the outer shell. So when your head hits the ground the only give for your head to transfer that force is into that EPS liner. If you have never looked in and felt that, do so because it is almost as solid as a rock. Yes it keeps your head from splattering all over the ground, but you will be slamming your brain into the side of your skull at a brutal force.
