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.

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.

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

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.
