ErgodyneSkullerz 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.

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.

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 sail dinghies and keel boats. I didn't want to wear a full helmet but still wanted to protect my head. Found these inserts and they have been a godsend. Anytime I sail I show people and they wind up buying them too. Even purchased 10 for our youth sailing program summer camp. The kids were thrilled to wear them after getting knocked in the head a few times without them. Absolutely worth the money. These have an opening in the back for a pony tail and can be trimmed down for smaller hats. They are adjustable since they have slits in them to allow them to expand or contract based on the user. They are also invisible (or nearly invisible if wearing a hat with some mesh) and very comfortable to wear. Don't hesitate to buy this if you or your kids sail. If I could give 10 stars I would.

Great product to have to protect my husband's noggin at work. He's a mechanic and when he's in a hurry he'll bump his head every once in a while so this is extremely durable and looks like it is made into his hats. So you can't even see it because it isn't visible. It is extremely comfortable and looks natural under his hats. It doesn't build up heat badly so he stays cool.

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.

After ordering this no more bumps and scrapes lightweight and comfortable I like it better with the backwards hat just remember to turn the cap the right way as well
