## Description

Ergodyne Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat, Charcoal - desertcart.com

Review: Works great! - I’m always bumping my head when I do projects around the house. So glad I found this item! Fits great in my cap, very comfortable and no more bumping my head and bleeding. I suggest using a little double sided tape to help attach it more firmly to the cap.
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.

### ⭐⭐⭐⭐ Works as expected
*by E***A on November 10, 2022*

I used this while corner marshaling at an SCCA race weekend recently. Helped keep my head warm and my wet cap off my head. Gives some surprisingly effective protection from bumping your head on low beams, getting smacked by balls of race rubber off racecars, etc. I put it in 3 different hats and it fit well in 2 of them - the third had a rivet keeping the back strap attached to the cap and it didn't allow the Skullerz from tucking into that hat. If you're using this in just one hat it's easy enough to trim the Skullerz to fit nicely in your ball cap, but if you want to use it in different ball caps then I found it fit differently in each cap, so consider each cap before trimming. I'm using it without trimming and it is acceptable in my flagging cap.
