Review: Title: I Bought the Ergodyne Skullerz 8945F(x)… Now I Fear No Cabinet Corner - Let me paint a picture: I’m in my garage, just vibing, when BAM, another stealth attack from the corner of a shelf I installed myself. That’s when I knew I had two choices: start wearing a helmet like I’m in a continuous episode of “Jackass,” or find something subtle that doesn’t make me look like I’m prepping for a medieval joust. Enter the Ergodyne Skullerz 8945F(x), the Tony Stark of bump cap inserts. It’s slim. It’s flexible. It slides into your everyday cap like it’s just chilling, but secretly it’s out here saving your brain cells from betrayal by doors, beams, and open hatchbacks. The first time I wore it, I tested it the only way a mature adult would: I headbutted a cabinet on purpose. (Okay, it was on accident, but let’s say it was research.) And you know what? No stars. No birds. Just a satisfying thud followed by smug silence. My hat didn’t even shift. I strutted off like I’d just won a bar fight with drywall. Comfort-wise, it’s weirdly impressive. It’s like a tiny turtle shell for your head, but breathable and discreet. I wore it for hours and forgot it was even in my hat until I took it off and flinched like my head had been abandoned. If you work in tight spaces, bump your head a lot, or just want to feel lowkey invincible while doing chores, this little guy is worth it. Bonus: you’ll look exactly the same, but with 100% more head protection and 78% fewer curse words shouted at inanimate objects. 10/10 would recommend. Cabinet corners, beware.
Review: Really helps protect from minor bumps - I ordered a pair of these in October 2023, and I write this review August 2025. I'm still on the first of the two-pack, and I have one inserted into a baseball cap 100% of the time I wear one, which is pretty much every day. So I have hundreds of hours of wearing this bump cap insert so far. I tend to hurt myself when I'm busy, overwhelmed, distracted, tired, or running late, whether it's bumping my head on something or stubbing a toe or running into a door frame or the edge of a table. These little cap protectors really work, and they've saved my head from probably dozens or hundreds of small bumps. Example: Have you ever opened your garage door only part-way because you just need to do something real quick and then stood up and bumped your head on it? Hurts pretty bad. Wearing an Ergodyne Skullerz bump cap insert really does absorb and disperse a lot of the force and shock that would otherwise be transferred to your head, taking it from an ouchie and potential injury to a nothing-burger. Have you ever tried to pick something up from under a desk or table and misjudged where the edge was when standing back up? Have you ever been working on your car and bumped your head? These really do work, and mine are still in immaculate condition (no scratches or cracks) after more than a year and a half, so it appears very durable. Caveat, these aren't helmets and obviously won't protect from serious forces, but for every day wear? Perfect. Not a single person has made a comment or noticed, so they are pretty much invisible under most caps. You can sort of see the gray on the back of the cap where you adjust the size of the cap, but it's not a big deal. Highly recommended and really do save your head from minor bumps.

## 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

### ⭐⭐⭐⭐ Excellent choice for electricians and carpenters and handymen
*by A***C on March 20, 2023*

I purchased this for my father, who works with electricians and plumbers and the like, and often finds himself surrounded by all manner of things you don't want to knock your head against. As such, this is a second-hand account. He reports that the cap is quite comfortable, fits in his hat without issues, and has given him no trouble. It isn't a hardhat, but that is not what it is for. It breathes well enough, it doesn't look all that hokey, and it is very lightweight, which means once you get used to it, you can about forget it is there. Based on that, I'd say this is a good buy. Anyone who has smacked their head on a rafter, stood up under a cabinet door, or had a hand tool dropped on their skull, knows how amazingly unpleasant an experience can be. If you are in a situation where that's likely to occur, this seems like a the right way to go.
