SpartanWear

The GBN Booster Club offers a great selection of clothing and other items that are emblazoned with our school name and/or Spartan logo. SpartanWear is sold at Parents Night in the Classroom, home football, and at various pop-up sales events throughout the school year. Follow our Instagram for timely updates on new SpartanWear apparel.

To order, please visit our Cheddar Up SpartanWear Sales Page or contact our SpartanWear Chair.

****NEW*****

Please note: It has come to our attention that some online marketplaces are selling unlicensed, high school-branded apparel, including for GBN. The only way to get OFFICIAL GBN Booster Club SpartanWear (which directly supports our school and athletic programs) is through our pop-up sales events or our Cheddar Up SpartanWear Sales Page. Accept no substitutes—if you or your student are looking for GBN apparel, please shop with us and keep your dollars in the community!
