Is Headgear required to play lacrosse?

No. Headgear remains optional in the US Lacrosse Youth Rule Book and in the USL/NFHS Rule Book. US Lacrosse women’s rules allow for the optional use of headgear if it meets ASTM standard F3137. The purpose of this allowance is to acknowledge that while women’s lacrosse is a relatively safe sport, the use of protective headgear is desired by some individuals. Please note that beginning January 1, 2017, only products that meet the ASTM standard will be regarded as legal for play.
