Intro Offer!


Worn by officials and umpires working in the highest collegiate conferences, including but not limited to the ACC, B1G, and SEC, the Core Energy Referee / Umpire Belt provides unmatched support for long days on the field, court or behind the plate.

Designed to elevate your IAP (Intra-abdominal pressure) to a point of super stiffness, enhancing energy transfer and optimizing muscle contractions through your body for faster movements and optimal support for your back and abdomen. This belt will help you reduce back strain, optimize your hip mobility, and improve your posture while letting you stay focused on the game.


  • PERFECT FIT: Available up to size 49" and comes with a customizable cut-to-fit guide. Tightening the belt provides more internal force, while loosening will give you more comfort and mobility. Experiment to find the tension that works best for you.
  • PERFORMANCE: These belts are designed to aid the engagement of abdominals and assist with hip alignment.
  • SUPPORT: Paired with a cut-to-fit system, this umpire belt supports your lower back without impeding movement.
  • COMFORT: The unique stretch material provides a comfortable and flexible fit around your waist, making it a preferred choice over ridged belts
  • HIGH-QUALITY MATERIALS: This umpire belt, designed by stacking 6 layers of CoreMesh material, provides the perfect balance between stretch and strength.
  • HARDWARE BUILT FOR PLAY: It features a high-quality silver buckle and synthetic leather that is built to last, making it ideal for rigorous use.
  • MADE IN JAPAN: These belts are manufactured in-house at our factory in Nagoya, Japan, ensuring high-quality craftsmanship.

Care Instructions

For cleaning, never machine-wash, machine-dry, or iron your belt. If your belt is dirty, we recommend wiping it down with a damp, lukewarm cloth, blotting it with a towel to remove excess water, and letting it hang in an open area to fully dry. 


  1. Record your waist measurement using a measuring tape. Always double-check your measurements to ensure a perfect fit.
  2. Measure from the middle hole to the end of the belt, and mark the point that is equal to your waist measurement.
  3. To account for the belt buckle, subtract and mark 2 inches from your waist measurement, then cut the excess material along this mark.
  4. Open the mouth of the buckle and insert the body of the belt. It should be ready to wear. 

*This product is not eligible to be returned once it is cut.*
