Information regarding boys and girls equipment can be found on the USA Lacrosse website. The USA Lacrosse Equipment Guide has the most up-to-date information about required equipment.
Used gear can be a great budget-friendly option, however, you will want to make sure the chest protector and helmet are SEI NOCSAE certified. There is quite a lot of used gear for sale that does not meet current requirements. RLC wants to help you avoid purchasing equipment that is unable to be used.
The chest protector will have a label like this:
Eyewear(goggles) for girls must be SEI certified.
Kindergarten Flex6 players will only require a lacrosse stick and a mouthguard.
Mouthguards are allowed to be any color, including clear or white, for girls and Flex6 players. Boys mouthguards are allowed to be any color, other than white or clear.
If you still have questions, please reach out to a youth coordinator for help.
