Ergodyne Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat, Charcoal : desertcart.ae: Tools & Home Improvement

Review: J'ai acheté cette protection pour mettre sous un chapeau en wingfoil. Elle passe très bien et ne bouge pas une fois le chapeau enfilé, et même après de grosses chutes. Je me suis déjà prit la planche et le foil sur la tête et bien je peux dire que ça protège très bien. On peut facilement découper la protection pour l'adapter à quasiment n'importe quelle casquette/chapeau/etc...
Review: I'm tall, so I end up hitting my head a lot at work. Fits nice under a brimless cap after a little trimming. It's got ventilation holes, but the wind really has to be blowing to evaporate the sweat that collects in it (the cap it sits in is mesh). It also has a foam rubber pad in the top to help absorb impact. It's lightweight, so you'll barely notice it's on your head. It seems sturdy. I doubt I'll have to buy another any time soon. Most importantly, no more scars and scabs on my head.

## Questions & Answers

**Q: Where are these manufactured?**
A: Hello, I just finished checking that information for you. The answer is: America!!! Congratulations your in luck I think. It will be on the inside of the bump cap. So, in conclusion, Go ahead and enjoy this American made product today! I know I'm loving mine. Have a great New Year!

**Q: Would this substitute (under a cap) for a skateboard helmet? Regular one's are so bulky and ugly.**
A: No it most certainly will not!   There unfortunately is no less bulky more stylish replacement for a real skateboarding helmet.  Save your brain and just buy a real helmet.

**Q: Does this have the same protection as the all-in-one safety cap?**
A: Thank you for your question. No, this insert is designed to protect against minor head injuries like bumps, scrapes, and bruises.

**Q: how do you wash it?**
A: With a wet rag

*by A***B on 24 June 2025*

Ottimo prodotto, sono molto soddisfatto dell'acquisto. Molto facile da adattare alla misura del cappello, si può tagliare comodamente con forbici (purchè siano ben affilate). Ho applicato la protezione ad un cappello che utilizzo per fare windsurf: è risultata molto più confortevole di quanto mi sarei aspettato, ed oltre a proteggere dagli impatti risulta anche molto fresco, grazie alla forma rigida cd ai fori presenti lateralmente passa molta più aria rispetto al cappello senza protezione. Non è molto economico, ma lo ricomprerei.
