Hammer Sports Official's Uniform and Equipment Guide

Ready to get on the field for Hammer Sports? Here's the gear you'll need to look the part. We stick pretty close to the uniform rules from the Minnesota State High School League (MSHSL). Sometimes, a specific league or sport will have a different requirement, so always pay attention to the details for that game. If you're not sure, ask your assignor.

Basketball
Volleyball
  • Shirt: A collared, polo-style short-sleeved shirt. The Hammer Sports uniform shirt is solid white or powder blue. For youth games a white polo is accepted.  If you are working with others on the game, please ensure all officials match uniforms.

  • Pants: Solid navy blue slacks.  Short are acceptable for youth games.

  • Footwear: Solid white athletic court shoes and solid white socks.

    Whistle: FOX 40 Classic CMG Whistle attached to a breakaway lanyard A spare whistle is recommended.

    Required Equipment: A set of yellow and red sanction cards, a flipping coin, and a ball pressure gauge. Line judge flags may also be required.

For Hammer Sports officials having properly fitted gear is essential for performance, safety, and a professional appearance. If you are new to officiating, we recommend a drive to Daves Sports Shop in Maple Grove for your uniform and equipment needs.

 

Their knowledgeable staff can provide expert advice and ensure you can try on items like chest protectors, masks, shirts, pants, and shoes before you buy. This is invaluable for first-time officials to guarantee a proper and comfortable fit.
