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

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.

I love my skull bump. I have had concussion after concussion after concussion after concussion after concussion. You can cut it to fit under your cap. I am soo so happy to have this. I should wear it all the time. Ive even bumped my head getting in and out of the car, multiple times at work on a shelf or shelves sticking out from the wall. Its really ridiculous how many times ive bumped my head. This is a life saver. When it storms i grab it snd feel that much safer from falling debris or just getting in and out of the car. I should put it under my work cap too. Might order another.

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.

I’ve purchased a few of these. I have to wear them in my ballcap at my workplace. It fits comfortably it my hat. It doesn’t make my head sweat during the summer time.

It fit perfectly into my $1.25 Dollar Tree baseball hat.No trimming necessary.

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 thing is a tight fit into your cap, and works better on newer caps. This holds your cap into a perfect dome shape. Protects your head from basement and attic assaults from above.PS if you're bald, you will sweat if you're the least warm, a LOT. But if it's cold outside, this keeps your head as warm or warmer then a stocking cap, nothing for your ears though, but matched with a hoodie, walking around all day in sub freezing temperatures in Frankenmuth, no problem. I know, not what you're buying it for, but a side bonus.When I don't where this, I bleed, low hanging ductwork or joists, crawl spaces, this thing saves you. Still jars the neck, but no stuck pig bleeding head wounds.

Inexpensive bumper for your cap.It works.for the minor bumps and scrapes.DO NOT IN ANY WAY THINK THIS IS FOR PROTECTING YOUR HEAD / BRAIN, IT IS NOT!It's to keep dings and dents off your noggin'.
