Good protection against small/slight bumps (in and out of a van all day long). Bought as a replacement insert for a port west (small peak) bump cap PS59 which it fits perfectly. Doesn't fit the large brim port west bump cap. Would buy again Review: Good protection & comfy - Fairly comfortable to wear and they do give that added protection. They also shape the caps well. ## 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 β€œtrim-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 | | Batteries included? | No | | Best Sellers Rank | 106,502 in DIY & Tools ( See Top 100 in DIY & Tools ) 77 in Hardhats | | Brand | Ergodyne | | Color | Anthracite Grey | | Customer Reviews | 4.6 4.6 out of 5 stars (3,816) | | Date First Available | 18 Aug. 2021 | | Department | Unisex | | Features | Lightweight | | Included components | 1 bump cap insert | | Item model number | 8945F(x) | | League | MMA | | Manufacturer | Ergodyne | | Material type | Polyethylene | | Number of items | 1 | | Product Dimensions | 21.59 x 17.78 x 12.7 cm; 90.72 g | | Size | Single | | Style | Single | ## Product Details - **Brand:** Ergodyne - **Colour:** Anthracite Grey - **League:** MMA - **Size:** Single - **Style:** Single ## Images ![Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat - Image 1](https://m.media-amazon.com/images/I/71bEewnsZTL.jpg) ![Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat - Image 2](https://m.media-amazon.com/images/I/71LXgS-4C3L.jpg) ![Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat - Image 3](https://m.media-amazon.com/images/I/81rsv0CgrrL.jpg) ![Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat - Image 4](https://m.media-amazon.com/images/I/81YRI+D3eBL.jpg) ![Skullerz 8945F(x) Universal Bump Cap Insert with Extra Venting, Fits Into Any Baseball Hat - Image 5](https://m.media-amazon.com/images/I/71mQs8jY4YL.jpg) ## Questions & Answers **Q: Does it work with beanies?** A: You'd have to have a long beanie to tuck the Bump Insert into as these slot into the seam/liner of a BB cap. It's possible but will likely shift about unless you find a way to lock it in position. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good insert *by K***N on 1 December 2025* Well vented.
