A baseball traveling at 90 mph can deliver 2,400 lbs of force. Other cups on the market can reduce that impact to 450 lbs of force—still enough to cause serious injury. The NuttyBuddy® protective cup has been proven in scientific tests to reduce that impact to just 110 lbs of force, which is within acceptable levels of impact.

A properly fitting cup shifts less, is more comfortable, and does not impede movement or performance. The unique, award-winning design of the Nutty Buddy Classic Athletic Cup more effectively and comfortably covers the male anatomy, while a full range of sizes - Boss, Hog, Trophy and Mongo - will help you achieve a perfect custom fit.

This cup is NuttyBuddy's most protective. Full high impact from any assault—front, side, and underneath. If you umpire or play a sport with a hard ball – Buy this cup. Ideal for baseball, hockey, and lacrosse. This is the beast that will keep you and your heirs safe.


  • Constructed of the same materials used in bullet-proof glass and military protective gear
  • Unique anatomical shape provides superior protection - a.k.a. Protecting the Boys®.
  • Cushioned edge for comfort and fit
  • Vented for additional comfort

In order to provide the utmost comfort and protection the Nutty Buddy, we recommend you wear your cup worn as a three piece system. To wear correctly, first put on compression base layer. Place jock and cup over the compression wear. Note: compression base layer and jock sold separately.

Took a one-bounce curve ball square to the cup in an 18U tournament game last night. Heard everybody groan, and someone tell the catcher to walk the ball out to the pitcher. It was great to be able to just say "nope, I'm fine, let's go". Great protection and so comfortable I can forget I'm even wearing it. What's not to like?

Comfortable, almost forget you have it on! Haven't impact tested yet, hope I don’t! But have heard it protects well!

Questions About This Product

Q: What is the difference in the Classic and the new flex?
– Patrick Williams

The sizing and shape of both models are the same. The flex cup has a larger rubberized edge which offers slightly more flexibility.
