Love it. - Finally, honest EMF protection! I was looking for a hat with 5G protection that didn’t screen EMF protection and this one is great as it looks like a normal baseball cap on the outside! This is the second RadiArmor product that I’ve tested personally, the other being the phone pouch and I like that the company discloses the real EMF protection as well as the theoretical protection. I also bought a 3 axis Tenmars RF reader to test stickers and cases from other companies that ‘claim’ 99.99% reduction and it wasn’t even close. Radiarmor claims the liner blocks over 99% and that the average reduction is 90%. This makes sense since you can’t cover your whole head! With my tests I got fairly close numbers to the average with anywhere from 75 to 95% depending on location and how you hold the reader. Being that most cell phone towers are above your head, I think that number is fairly accurate. The hat is also very comfortable and doesn’t feel like any extra weight. I wear hats all the time and this one is my new favorite! Review: Nicer than expected. - I put my phone in with an app that shows relative signal strength and it cut it down even though it is not a closed bag/ is half open. A bit large, but just right for me as it protects right to the top of my ears. Streamline metal latch for matching cloth tightening strap that tucks in easily. Solid hat. Not wee like a ball cap but not too bulky like a trucker hat either. Middle of the road every-day hat that just looks like a normal hat and does not stand out. Recommended. ## Features - OVERVIEW – RadiArmor’s unisex EMF blocking hat features a breathable liner made of woven silver fibers that blocks over 99% of high frequency RF and millimeter wave radiation commonly associated with WiFi, cellular and 5G communication. - LAB-VERIFIED SHIELDING: Lined with a breathable woven silver fabric, independently tested to block 99.9% of high-frequency RF radiation (providing over 90% average reduction to the head). Please Note: This hat shields your head, not your entire body. For accurate home testing with an RF meter, always place the reader directly inside the hat (see full testing instructions below). - INTEGRITY: Many EMF protection products claim 99% reduction but are referring only to the radiation blocking material itself, NOT the protection you receive. Wearing a pendant that blocks EMF offers as much a protection as a waterproof pendant would protect you in the rain. At RadiArmor, we only make EMF protection products that provide real protection. - SIZING – This unisex hat features an adjustable strap and is designed to fit most small to medium size heads. May not be suitable for size XL. Please see size chart. - CARE – Silver is naturally odor resistant and rarely requires washing. If necessary, hand wash and hang dry only. Silver naturally changes color over time but this does not effect the EMF shielding capabilities. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08BZ6DC55 | | Additional Features | Adjustable | | Age Range Description | Adult | | Apparel Closure Type | Buckle | | Apparel Fabric Stretch | No Stretch | | Apparel Fabric Weight Class | Lightweight | | Best Sellers Rank | #132,306 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #48 in Medical Face Shields | | Brand Name | RadiArmor | | Care instructions | Hand Wash Only | | Closure type | Buckle | | Color | Black | | Customer Reviews | 4.0 out of 5 stars 277 Reviews | | Fabric Type | Cotton, Silver | | Fabric type | Cotton, Silver | | Fit Type | Regular | | Fit to Size Sentiment | Generally Positive, May Not Fit XL | | Hat Form Type | Baseball Cap | | Import Designation | Imported | | Is Waterproof | True | | Item Dimensions | 9.06 x 7.87 x 3.94 inches | | Material Type | Cotton | | Number of Items | 1 | | Occasion Type | Birthday | | Origin | Imported | | Pattern | Solid | | Pattern Style | Solid | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | outdoor | | Seasons | All | | Sleeve Length Description | Sleeveless | | Style Name | Baseball Cap | | Theme | Sport | | UPC | 799209376176 | | Unit Count | 1 Count | | Water Resistance Level | Not Water Resistant | ## Images ![RadiArmor EMF Blocking Hat – Unisex Hat with EMF Blocking Liner That Blocks Over 99% of High Frequency RF Radiation - Image 1](https://m.media-amazon.com/images/I/61Gpp-ESQdL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Hi, please respond only if your answer is certain.. facts please, no opinions. the sizing chart includes a "fitted" option. how do i select it?** A: Thank you for your question. The only baseball style cap we offer uses an adjustable strap. The fitted column on the size chart indicates the equivalent range this hat can adjust to. **Q: What type of fabric is use here? titanrf faraday fabric?** A: We use RadiArmor Shielding made with 99.9% pure silver. Most faraday fabrics, including ours, are made using a combination of copper and nickel to keep costs down, but they are not well suited for clothing. Silver is more expensive but can be made thinner and more breathable. Silver also offers better anti-bacterial properties. **Q: How big is the emblem?** A: It's approximately an inch tall. **Q: What kind of material, (polyester, cotton) is the front quarter of the inner liner made of that touches the forehead?** A: The stiffener in the front quarter panel are made of Oxford polyester. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic product; Does the job!
