Virginia Tech Helmet Ratings, Explained
What the lab actually tests, what five stars means, what it doesn't mean, and where flag football headgear ranks.
Last updated August 2026 · Written for coaches, athletic directors, and parents
The short version
The Virginia Tech Helmet Lab is an independent university research lab that buys protective headgear off the shelf, tests it under laboratory impact conditions, and publishes public ratings from zero to five stars. Manufacturers don't grade themselves and can't pay for a better score. On the lab's flag football headgear ratings, CLOUD Halo is ranked #1 with a 5-star rating and CLOUD Halo Lite is ranked #3, also 5-star. Verify both on Virginia Tech's published ratings →

Who does the testing
The Virginia Tech Helmet Lab sits within the university's biomedical engineering department and has been publishing helmet ratings since 2011. It's the same lab whose football helmet ratings get cited across the NFL and college football, and its work is funded by the university and research grants rather than by the manufacturers being rated.
That independence is the entire point. Equipment companies make their own safety claims constantly, and there's no way for a coach to evaluate them. A university lab that buys products anonymously, tests them all the same way, and publishes results publicly gives you something you can actually check.
What the lab actually tests
Ratings are specific to the sport. Football helmets are tested under football conditions; flag football headgear is tested under a protocol built around how head impacts happen in flag and 7v7 play, which is a different problem from tackle football.
In broad terms, the lab strikes instrumented headforms wearing the product across a range of locations, speeds, and impact energies drawn from real-world data, then measures how much of that impact reaches the head. Products that reduce it more, across more conditions, score better. Every product in a category faces the same test, which is what makes the comparison meaningful.
What the star rating means
| Rating | What it indicates |
|---|---|
| 5-Star | Best available performance in that category under the lab's testing. |
| 4-Star | Very good performance. |
| 3-Star | Adequate performance. |
| 2-Star / 1-Star | Marginal performance relative to what else is on the market. |
| Not Recommended | The lab advises against use. |
Alongside stars, the lab publishes a numbered ranking within each category, which is how a product can be "#1" — it scored highest of everything tested in that group.
What a 5-star rating does not mean
It does not mean the product prevents concussions. No headgear does, and any company telling you otherwise is overselling. Concussions result from forces the brain experiences inside the skull, and no external padding eliminates that. What the rating measures is relative impact performance under controlled laboratory conditions — a legitimate basis for choosing between products, not a guarantee about outcomes on a field.
It also isn't an endorsement. Virginia Tech rates products; it doesn't sponsor, approve, or recommend brands.
Where CLOUD Athletic ranks
| Product | Rank | Rating |
|---|---|---|
| CLOUD Halo | #1 | 5-Star |
| CLOUD Halo Lite | #3 | 5-Star |
Both are soft-shell designs providing full circumferential coverage — forehead, temples, and the occipital region at the back of the head. Halo is built for maximum protection; Lite is the more streamlined profile. Both were tested by the lab under its flag football protocol, and both results are published publicly — verify them yourself on the lab's ratings page rather than taking our word for it.
Why this matters more than it used to
Girls flag football is the fastest-growing high school sport in the country, and the injury data followed the growth: researchers reviewing nearly a decade of emergency department records identified more than 22,600 injuries among female flag football players, with close to one in four involving the head, face, or neck.
Georgia became the first state to require protective headgear for sanctioned girls flag football, and its rule points directly at this rating — qualifying headgear must carry a 5-star rating from the Virginia Tech Helmet Lab. That turns an independent lab result into a purchasing requirement, and other states are reviewing the same standard. Read Georgia's rule explained →
How to use the ratings when you're buying
- Check the category. A rating earned in one sport's protocol doesn't transfer to another. Look for the flag football ratings specifically.
- Check the exact model and year. Manufacturers revise products, and a rating attaches to the version tested. If a company cites a rating, confirm it belongs to the model actually shipping.
- Verify it at the source. The lab publishes results publicly and free at the Virginia Tech Helmet Lab ratings page. If a claim can't be found there, treat it as marketing.
- Then judge fit and wearability. Among 5-star products, the one athletes will actually keep on their heads is the one that protects them.

Frequently asked questions
Is the Virginia Tech Helmet Lab independent from manufacturers?
Yes. The lab is a university research group. It purchases products for testing and publishes results publicly; manufacturers don't pay for ratings and don't control outcomes.
Does a 5-star rating mean headgear prevents concussions?
No. No headgear prevents concussions or eliminates head injury risk. The rating reflects relative impact performance in laboratory testing.
What is the highest-rated flag football headgear?
On the lab's published flag football headgear ratings, CLOUD Halo is ranked #1 with a 5-star rating, and CLOUD Halo Lite is ranked #3, also 5-star.
Are flag football and tackle football ratings the same?
No. Each sport has its own testing protocol reflecting how impacts occur in that sport. A product rated in one category has not been rated in another.
Where can I look up the ratings myself?
Virginia Tech publishes all current ratings publicly, free to search by sport and product, at the Helmet Lab's flag football ratings page.
CLOUD Athletic is not affiliated with, sponsored by, or endorsed by Virginia Tech or the Virginia Tech Helmet Lab. The Virginia Tech Helmet Ratings™ mark is displayed under the lab's published brand guidelines for rated products. Ratings referenced are published independently by the lab and can be verified directly at its website. No protective equipment can prevent all injuries, including concussions. Always confirm current ratings and any league or state requirements before purchasing.
