The Schutt Ion 4D helmet is a football helmet made by Schutt Sports. The helmet includes an integrated face guard and cushioning designed to absorb extra energy upon impact. Schutt claims the cushioning makes the helmet especially comfortable to wear.
Schutt Sports created the first face mask for a football helmet in 1935. However, in 2008, sports gear manufacturer Riddell sued Schutt for patent infringement, claiming that the Ion helmet had been copied from Riddell. Schutt countersued but lost the suit and had to file for bankruptcy. Schutt has done a lot of research and product development to try to prevent concussions in football; nevertheless, its helmets contain warnings about serious brain and neck injuries that can occur when participating in the sport.
