2019 Washington State 4A Semifinalists


Online Player-only Store is live – will close on June 26

The Player-only store (with gear and apparel designed just for our players) is now open.  For each item purchased, a small percentage is rebated back the Mt Si Football boosters and is one of our many fundraising efforts.  This online store is for PLAYERS ONLY.  

For families and fans, we will open a different site with gear designed specifically for our community. 

For players new to the program (incoming Freshman or new players):  Each year the coach picks a Game Day piece of clothing that each player wears on game day.   This year we are choosing the same 1/4 zip sweatshirt we used last year.  So if you played last year, you DO NOT need to purchase a game day 1/4 zip sweatshirt.  If for reason you did not purchase a 1/4 zip game day sweatshirt last year or you are NEW to football this year then you NEED to purchase the 1/4 zip game day sweatshirt.  It is the first item listed on the player store.  If you are in need of a full or partial scholarship then please email Heidi Beth Billingsley ( We want every player to have this for Game Day. 

Orders will be fulfilled near the end of July.  The booster club will coordinate a pickup program once all of the gear and apparel has been received.
