Description
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® Flex 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 Flex Cup more effectively and comfortably covers the male anatomy, while a full range of sizes – Hog, Trophy and Mongo – will help you achieve a perfect custom fit.
For those who need more give in their protective cup, go for the FLEX. Originally designed for MMA fighters, this cup is designed for even more comfort and flexibility.
FEATURES
- Constructed of the same materials used in bullet-proof glass and military protective gear
- Unique anatomical shape provides superior protection
- Flexible, rubberized 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 flex 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.
