Gregg Easterbrook has the details from a Virginia Tech comparative study of football helmets:
Researchers at Virginia Tech have produced the first brand-by-brand, model-by-model ranking for the likely concussion resistance of helmets. A star-rating system modeled on crash safety rankings for automobiles, the rankings clearly identify the best and worst helmets. Virginia Tech researchers give high marks to these helmets: the Riddell Speed, Riddell Revolution, Riddell Revolution IQ; the Schutt Ion 4D and Schutt DNA; and the Xenith X1.The Virginia Tech researchers give medium grades to the Schutt Air XP and Schutt Air Advantage. The Virginia Tech rankings warn players not to wear these helmets: the Riddell VSR4 and the Adams A2000.
Now the chilling part: the VSR4 — Virginia Tech’s second-lowest-rated helmet — was the most common helmet in the NFL last season. The VSR4 is widely worn in college and high school, too. Immediately after the Virginia Tech findings were released, Riddell advised football teams to stop using the VSR4, long the company’s best seller.
(The new Rawlings line of football helmets was not on the market in time to be included in the study. Virginia Tech will rank Rawlings helmets — which from the start is promoting safety features rather than styling — next year.)
