## Description

Ergodyne Skullerz 8945 Universal Bump Cap, Gray - desertcart.com

Review: Fits great and works – saved me from bumps already - This insert is exactly what I needed for work. Slides right into my regular baseball cap and you barely notice it's there. Lightweight and comfortable. Took a few minutes to trim it to fit my hat perfectly. Now I forget I'm wearing it – until I bump my head on something and realize it actually works. Had a couple of close calls that would've hurt without it. Good ventilation too. Doesn't make my head sweat like I expected. Solid value for the price.
Review: AWESOME!!! - 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.

## Questions & Answers

**Q: is this osha approved?**
A: No, this product is not OSHA approved.

**Q: Would this have prevented my 5 staple laceration from the impact of a pry bar i was pulling on over my head when the bar slipped off the anchor point?**
A: I’ve never had a crow bar hit my head with one of these things on so I wouldn’t know about that. However, due to my work in confined spaces, I’ve hit my head on fat industrial studs that were protruding from the wall or ceiling pretty good and this bump cap protected my head from any lacerations/damages.

**Q: Which one bump hat osha approved?**
A: This cap is by no means a safety hat as required on construction sites, however, it is perfect when working in attics, crawlspaces or any other tight space that you may be bumping your head.  I use when inspecting crawlspaces and have tested it many times bumping a beam and it doesn't hurt as bad if no cap worn.

**Q: Has anyone put this under a Carhart cap? If so, did it fit?**
A: Yes it does fit the Carhartt. Specifically I have the flexfit hat.
