Review: A must have, one of the best for the price. - I needed these for a job that requires hard hats or bump caps. After wearing a hard hat for the first 2 days i was annoyed, and seeing other people who worked at the facility every day wearing bump caps I asked about them. Before this i didn't know they existed. I couldn't believe how comfortable it was compared to a hard hat. They're easy to install in a hat and being able to cut the sides to adjust them is pretty cool. It saved my head a twice when going up on a 26' lift (i bumped my head on a sprinkler pipe lol). Because it's ventilated i didn't get to sweaty and the thickness of the cap is a little thicker than other ones I've seen but thats a good thing. Once you put it in your hat its very sturdy. It has a piece of foam inside and if you wanted to you can add more. This really made my job easier ( if you wear hard hats you know what I mean) even if only a little I definitely recommend it. Review: It works. - Fits into a variety of hats (as it should). It provides complete, consistent, excellent protection against instances of self-generated force (e.g. accidentally banging your head on steel shelving). I had to trim it to fit better, but it was along the intended area to trim for those with smaller heads. ## Features - NEXT GENERATION BUMP CAP – Improves upon design of best-selling Skullerz 8945 Insert for enhanced breathability and up to 35% more crown impact protection - LIGHTWEIGHT HEAD PROTECTION – Guards against bumps, scrapes, bruises and other minor head injuries - ENHANCED IMPACT PROTECTION – Ribbed top improves top-of-head protection by up to 35% - MAXIMUM BREATHABILITY – All-over venting enhances airflow to keep wearers cool - POLYETHYLENE SHELL - Durable material resists breaking and cracking - FITS ANY HAT – Patented “trim-to-fit” design easily adjusts insert height to fit different cap designs - FLEXIBLE – Horizontal and vertical two-way flex design for protection that is not stiff or bulky ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09D16Q74W | | Best Sellers Rank | #2,839 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #12 in Head Protection Equipment | | Brand | Ergodyne | | Brand Name | Ergodyne | | Closure Type | Pull-On | | Color | Charcoal | | Customer Reviews | 4.5 out of 5 stars 3,517 Reviews | | EU Spare Part Availability Duration | 5 years | | Included Components | 1 bump cap insert | | Item Type Name | Universal Bump Cap Insert - Extra Venting | | Item Weight | 3.2 ounces | | League | MMA | | League Name | MMA | | Manufacturer | Ergodyne | | Manufacturer Part Number | 23481 | | Material Type | Polyethylene | | Model Name | Skullerz 8945F(x) Universal Bump Cap Insert - Extra Venting | | Model Number | 8945F(x) | | Number of Items | 1 | | Size | Single | | Style | Single | | Style Name | Single | | UPC | 720476234814 | | Unit Count | 1 Count | | Warranty Description | We stand behind everything we make and guarantee our products to be free of defects in materials and workmanship to the original purchaser for the lifetime of the product.

This really made my job easier ( if you wear hard hats you know what I mean) even if only a little I definitely recommend it. ### ⭐⭐⭐⭐⭐ It works. *by I***C on June 28, 2026* Fits into a variety of hats (as it should). It provides complete, consistent, excellent protection against instances of self-generated force (e.g. accidentally banging your head on steel shelving). I had to trim it to fit better, but it was along the intended area to trim for those with smaller heads. ### ⭐⭐⭐⭐ Better to have it and not need it. *by M***A on April 5, 2026* It’s lightweight, easy to fit into pretty much any hat, and gives you that extra protection from bumps and low clearances without having to wear a full hard hat. It’s not bulky either, so it’s comfortable enough to wear for long periods on the job. The trim-to-fit design is nice too it actually lets you get a good fit depending on your hat. The protection is legit for what it’s meant for just everyday jobsite bumps and scrapes. Definitely something I’d keep in my hat if I’m working in tighter areas. Only downside is the breathability in the summer. Even though it has vents, your head can still get pretty hot when you’re out in the heat all day. The airflow helps a little, but not enough to fully keep you cool. Overall, it’s comfortable, useful, and adds a good level of protection you just might feel it more when it’s really hot out. ## Frequently Bought Together - Ergodyne Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat, Charcoal - Ergodyne Skullerz 8945 Universal Safety Bump Cap Insert, Lightweight, Fits Into Any Baseball Hat - GREEN DEVIL Matrix Lite Series Bump Cap Insert for Baseball Caps EN 812 Universal Safety Bump Hat Insert for Men Women Vented Lightweight --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://grenada.desertcart.com/products/366827266-ergodyne-skullerz-8945f-x-universal-bump-cap-insert-with-extra](https://grenada.desertcart.com/products/366827266-ergodyne-skullerz-8945f-x-universal-bump-cap-insert-with-extra) --- *Product available on Desertcart Grenada* *Store origin: GD* *Last updated: 2026-11-11*
