Check out these super light football helmets that promise twice the protection against concussions from SG Helmets. These helmets for youth football players are half the weight of other helmets on the market. They brag that it’s a 2.5lb lighter helmet made of polypropylene and the outer shell is like a race car helmet. However, they do not lower the impact according to a study done by researchers at Purdue University. They are comparable in cost at $350.00 per helmet.
