Designed to look and feel like a normal everyday beanie. An eco-friendly choice designed with comfort in mind. - INDEPENDENTLY LAB-TESTED & HOW TO VERIFY YOURSELF: The EcoShield fabric has been evaluated across a frequency range of 30MHz to 10GHz, including testing in the US using IEEE 299 methodologies. Results recorded attenuation levels as high as 99.99 percent within the measured range, with peak attenuation 78 dB. For those wishing to conduct their own testing, a quality meter is needed. Please note-cell phones are not a reliable way to test. If your cell still rings it doesn't mean it isn't working. - CREATED BY AN AUSTRALIAN FAMILY BUSINESS WITH CERTIFIED EXPERTISE: Golden Kocoon was founded by Jenny and Dave, a certified E.M.F Technician with Building Biology training.

I put my clothes with cold water Tide. I then put the dryer on air dry. I have had no problem. **Q: What percent copper does the protective lining have?** A: If you read the contents on the hat, it reads that the interior liner has 40% silver, 50% bamboo, and 10% spandex. (do not see copper listed on there). **Q: When will grey hat be in stock?** A: Hi T/D, we have more grey beanies landing sometime in August. I will reply here again once they are available so you know :) **Q: is delivery time really 1-2 months?** A: Once a tracking number is created it is in the US and on the way to the Amazon warehouse. This is when Amazon can say it is available in 1-2 months to be super safe, as it can at times take 2 weeks+ sometimes to check in once it gets to them (depending on time of year). This particular shipment is only a few days from the warehouse, so hoping they are closer to 2-3 weeks (tops) until being able to be shipped to customers. If you check in every few days it will change suddenly when they clear from 1-2 months to 3 days! Hope this helps :) ## Frequently Bought Together - Golden Kocoon®- E-M-F Organic Cotton Beanie with EcoShield™ Tech Bamboo Lyocell Faraday Fabric Silver Liner- Adult Size Hat in Black -5 g, BT, Smart Meters & WiFi- Cocoon Cap - Golden Kocoon®- E.M.F Cap Hat- Bamboo Faraday Fabric Liner- 5.g, Cell Towers, Bluetooth, Smart Meters & WiFi - Golden Kocoon® - E-M-F Organic Cotton & Bamboo Viscose Slouch Beanie with EcoShield™ Tech Bamboo Lyocell Faraday Fabric Silver Liner - Adult Size Hat in Black - 5 g, BT, Smart Meter & WiFi Cocoon Cap --- ## 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://www.desertcart.jp/products/394917057-golden-kocoon-e-m-f-faraday-beanie-organic-cotton-bamboo](https://www.desertcart.jp/products/394917057-golden-kocoon-e-m-f-faraday-beanie-organic-cotton-bamboo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
