Nutshellz® Level 1 groin protectors are worn by many MLB umpires. The several we spoke with about these bullet-resistant cups highly encouraged us to offer it.

While plastic athletic cups can break and cause serious injury, Nutshellz are indestructible. Handmade in the U.S. with the world’s strongest military-grade materials such as Kevlar, carbon fiber and aero-space epoxies, it can stop a 100+ MPH fastball in its tracks and provides umpires with the highest level of protection on the market.

  • Engineered with an elongated shape for proper placement, stability and mobility
  • Ergonomically correct design with urethane comfort surround edge protects against discomfort on the field

Nutshellz Level 1 Armor Protective Cup - Kevlar & Carbon

In this video you will see the Adult Level 1 athletic cup, hand made in the USA utilizing an innovative small batch manufacturing facility located in High Ridge, Missouri. This cup is strong enough to stop real bullets, but it’s designed with “YOU” the umpire in mind. The Nutshellz Level 1 Armor Protective Cup is recommended to any umpire wanting to find durable, comfortable groin protection. The cup features a narrow tapered shape that extends further between the legs allowing for the most natural fit possible. What this means for you is that Nutshellz cups won’t pinch or rub, making Nutshellz extremely comfortable...especially when pair­­­ed with the Nutshellz Compression Jock Shorts. Nutshellz cups offer the strongest protection available because they use the highest-grade materials available, like Ballistic grade Kevlar, Carbon Fiber, and Aerospace grade epoxies.

I like this cup. It doesn't crack, but it keeps me safe. Although, it doesn't fit into the cup pocket very well.

Best protector I've ever used in my life and fits great in the MMA jockstrap. Regardless of the compression shorts you feel 100% protected.

Questions About This Product

Q: What's better, one of the NuttyBuddy cups or the Nutshellz cup? What one is longer lasting and stronger?
– Jayden Morrison
Both will provide excellent protection. Nutshellz is graded as most protective featuring a layer of Kevlar, carbon fiber and aero-space epoxies. The longer lasting aspect would best be related towards the supporter system. The Nutshellz will need an alternative jock while the NuttyBuddy has a 3-part supporter system.
