Optional gear listed on US Lacrosse link above.
an extra stick at your house for playing catch is also recommended BUT a good mitt will also work

Where to buy (some recommendations beyond the big box stores):
Specialty lacrosse stores

Used sports equipment stores like Play It Again Sports - please familiarize yourself with modern sticks and don't buy earlier models 

Goalie Gear:  

Each coach is supplied with gear by MYL to legally protect your daughter when playing this position.  Many times she will play half  of the game & another girl will switch with her. 

*If your daughter has a skin infection on any given day that is contageous, please notify the coach so that we have her play goalie on a different day.  Open & healing wounds should be covered at all times while playing.  We recommend bring a close fitting long sleeve shirt to wear under the goalie equipment.   The CDC is a great source of up to date medical information about risk & precvention .  Here is an example for ring worm - fungus:  https://www.cdc.gov/fungal/diseases/ringworm/risk-prevention.html
