### ⭐⭐⭐⭐⭐ Good protection and good price
*by R***E on December 27, 2025*

Good quality, good price, and good protection for your head. It has saved many many times from cut my head from hitting it on something. Fits in my hat well.

### ⭐⭐⭐⭐⭐ Head cap built in!
*by J***. on February 27, 2026*

Great little head protector that fits perfectly into my business baseball cap. It’s great!! Knowing I can be in the field working and pull my hat off to show safety people that I have a hard hat built in.

### ⭐⭐⭐⭐ Neat product to keep from bashing your head !
*by G***R on September 27, 2023*

Neat product to keep from bashing your head on pipes etc...however...the inside top portion that is nearest the crown of your head is unprotected...meaning...there should be some sort of thin rubber against your scalp. The plastic actually feels rough on us bald guys who buy something like this to protect our bald heads. Otherwise, it fits in my work ball cap well...except for the very rear (which IS padded for some reason). It shows out the back of the cap. I took some scissors and cut that portion out and rounded it off so it wouldn't cut into me. I like the concept and it feels ok...so I might order a few more if this one works out. I was initially looking for a lightweight helmet to wear and found these "Bump Caps." They have a lower rating than OSHA rated helmets, but for what I needed they fit the bill exactly ! I'm in engineering and infrastructure rooms occasionally and have bashed my head on pipes, fittings, etc...etc...etc These WILL protect your noggin from these type items by just wearing a ball cap, like I wear all the time anyway. Most of these will need some "fitting" but that's just trimming the edges with scissors and sticking them inside your preferred cap. They feel fine, but I also ordered some "hat size adjusters" (foam strips with adhesive backing on them) to stick inside the top of the bump cap to make it a more customized fit. If you're in Engineering spaces, you won't regret getting a few of these !
