Experimental Helmet Designs

To help prevent and reduce concussions, researchers are designing new helmet concepts.

Slideshow: The Bulwark Helmet, developed by Michael Princip, is a segmented design that resembles the stitching patterns of old leather helmets. The segments can be fit with different types of padding to fit players’ needs.
Slideshow: Layers of padding inside the Bulwark helmet vary in thickness and density. The layer just beneath the outer shell is called an absorption band and is made of a mix of thermoplastic urethane and foam. The materials are calibrated to offer the right amount of shock absorption to avert energy from reaching the innermost shell that surrounds a player’s head.
Slideshow: The innermost layer of padding in the Bulwark is a type of foam that cushions the head and secures the helmet in place.
Slideshow: Brett Straus, who works for at Protective Sports Equipment, has spent eight years developing the Gladiator helmet. It has a soft outer shell made of polyurethane foam over a hard shell. It also includes several layers of protection on the inside.
