GREEN DEVIL Matrix Lite Series Bump Cap Insert for Baseball Caps EN 812 Universal Safety Bump Hat Insert for Men Women Vented Lightweight

muy bueno, ligero, con ventilación suficiente, el diseño permite utilizar conchas auditivas sin que moleste; altamente recomendable

So I use this daily at work and for the price it's beats the bump cap that the company provides by a huge margin. It's lighter, you can put it in pretty much any hat you own and swap them out when they get dirty. It's comfortable, easily fits any of my hats, and you can't even tell it's there so it looks good. It's not expensive like any of my hard hats, and it's save my noggin a few times already when I wasn't paying attention and ran into something. Easy to use and functional without breaking my wallet makes it a no brainer.

This seems ridiculous to use, but it is so worth it. I live the RV life, which is renowned for sharp points that can leave head scars. This is a game-changer. Fits inside any hat. More comfy than I imagined. I use it regularly. It's saved me from many scars already! Well built, long-lasting. When inside my hat, it is unnoticeable to anyone looking at you.

It’s good. Didn’t fit well under most of my hats but otherwise it seems like it offers nice lightweight protection for the money. Vents nicely.

Works great and has saved my noggin quite a few times in attics and crawlspaces. I did have to use a bench grinder to shave the edges down so it would fit in my company hat better. I'd estimate I shaved about 1/2" all around.
