FAQs on Women's Headgear

What does the ASTM standard mean?

The ASTM standard is the first-ever performance standard for women’s lacrosse headgear, developed to help reduce impact forces associated with stick and ball contact in women’s lacrosse. See the timeline of headgear development.

Who are ASTM and SEI?

ASTM and SEI are independent organizations that develop performance standards and certify products to help ensure player safety. Please visit the SEI website for a listing of models that have submitted a passing report compliant with ASTM F3137 and are deemed legal for play.

Will the headgear prevent concussions?

The headgear standard was developed to decrease ball-to-head and stick-to-head impact forces. No headgear or helmet in any sport has been proven to prevent concussions.

Is the use of headgear required?

No. Headgear remains optional in the USA Lacrosse Youth Rule Book and in the USAL/NFHS Rule Book.

What does the headgear look like and what does it cost?

The ASTM performance standard requires the headgear to fully cover the head, thus precluding the head band type of products used by some players. Some headgear may have integrated eyewear; any headgear used must be worn with required eyewear. The standard has two options, allowing manufacturers to make their headgear with the eyewear implemented or a product that is compatible with various eyewear products currently on the market. Products vary in cost and design.
