Ergodyne Skullerz 8945 Universal Safety Bump Cap Insert, Lightweight, Fits Into Any Baseball Hat

I am an auto mechanic and very frequently I bump my head on the underside of vehicles. I have had many cuts and lacerations to my head from various things under the vehicle or from bumping my head on the lift arms when standing up.Last Wednesday I hit my head on the lift again and caught the sharp edge when I did. Not only did it hurt like crazy but it left a nasty knot on my head. I finally decided to look into something that may help me out. I came across this product and since it was relatively cheap decided to give it a try. It arrived within 2 days (thanks prime!) and I used it for the first time yesterday. I did have to trim the sides as it’s fairly tall, that was very simple since there are guide marks for cutting. Once I had trimmed it I installed it into my hat and it fit perfectly.While wearing it I completely forget that it’s there. It does not squeeze, pinch, or rub in anyway. The foam insert on the top adds comfort and helps to keep my hat in place. I did not notice any added heat from it either, it seems to vent very well and is light enough that it isn’t like wearing a helmet all day. It is also invisible, no one can tell that it is in my hat and really, by looking in the mirror I confirmed that if I didn’t already know it was there I would have no clue from the looks of the hat.Finally, I realize that this isn’t a safety helmet, it isn’t going to offer me any protection if something were to fall on my head BUT that isn’t why I bought it. I confirmed that it does indeed do what it says it will. I bumped my head under a car on the first day that I had this piece in my hat and I felt nothing! No cut, no bruise, no ouchie. It did EXACTLY what I wanted it to do.I highly recommend this to anyone who works in the auto mechanic field or anyone who bumps their head from time to time. I truly wish that I had discovered these a long time ago.

This fits perfectly in a standard baseball cap and connot be seen. I use it when cutting wood, working on the car or doing yard work. Breathes well and is not heavy but protects from minor bumps and knocks on the noggin

Absolutely love this! I chronically bump my head under the hood while wearing a ball cap, or when exiting my skid steer! The worst is when the button on top of the hat nails you right in the middle of the head! I don't want a big skull cap like we used to wear on the flight deck. This is the perfect solution! Completely concealed within my ball cap. HIGHLY RECOMMEND.

This was really easy to insert after cutting it to the appropriate size and keep it in your cap. For most caps the insert will not make it look any different but is visible under the mesh for trucker caps. It does seem to add a bit of protection for my head but it makes my cap warmer and I'll sweat a lot more with this on. Finally, this didn't seem like it was brought up but it does add weight to the cap and can feel uncomfortable the first few time wearing it. And of course if this cap falls onto the ground it will make a hilarious thud when other people around expect it to be a regular cap.

I love these helmets. They are light weight and flexible. I have sleep apnea and need to wear a chin strap. The chin strap, of course, runs over the top of my head and was creatng a dent in the top of my skull. It would mess up the way my hair would lie. I looked like there was a "saddle" on top of my head... lol. I use this helmet under the chin strap strap that runs over the top of my head. No more dents in the top of my head and my hair brushes out beautifully. You can cut this helmet to custom fit. I wear it every night and couldn't be happier that I found it. It make my sleeping so much more comfortable. I am a builder, and also use this helmet under my cap (Which it was designed for) and it helps protect me from head trauma should my head get hit on the job. It's a great contribution to my life.

These ergodyne skullerz are great. I have a problem with ball caps fitting properly usually they are to big. I like a crisp tight look on caps, these inserts shape the cap perfectly making a nice fit while maintaining the shape of the cap, no sagging in the back and a nice comfortable fit. Sharp look. Highly recommended.

I've had to wear military Safety Cranial Protection for about 15 years of my Navy Service. If I had this for when I was doing non-aircraft vehicle maintenance or stuff that required a bit of head protection for banging into things it's a perfect thing. Light Weight and Flexible to fit under a baseball (or duck bill cap as the EU calls it, since they don't have Baseball there). It's the perfect balance of basic protection without sacrificing comfort to wear for all day. However, it does cause a lot of sweat collection to occur on really hot days even light color doesn't help; so you feel like your brain is baking even with a mesh backed ball cap.From Automotive Maintenance & Repair to DYI &Home Maintenance to Moving Furniture Work; this is a GENIUS idea for protecting your head from minor bumps and bruises. For Example: Having someone drop a tool on your head or hood (bonnet in the EU) of the vehicle deciding to drop without warning.As well as working under a vehicle to protect yourself even with a hard hat on top as extra protection (Oil Change or other under vehicle maintenance).I would have love to also used this as additional protection when I was a Park Ranger (Security) at the remodeling of the buildings at my job site. While I was never directly in a construction area most days. The fact that this would have been great to wear for walking around and having a branch or other item drop on my head just out walking around in the wilderness.
