It does not protect you from EMF. I tested it with my Trifield meter. I put my cell phone in the hat and it rang non stop ! Pure fraud! ### ⭐⭐⭐⭐⭐ Winter cap *by M***R on Reviewed in the United States on November 9, 2019* Great protection. Thank you. ### ⭐⭐⭐⭐⭐ J'adore ce produit *by D*** on Reviewed in Canada on October 14, 2020* J'aime la texture fine de cette tuque et la couleur. En plus me protège des ondes qui sont autour de moi. --- ## 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.pl/products/123973412-lvfeier-high-elastic-rf-emf-wifi-shielding-wool-thickening-cap](https://www.desertcart.pl/products/123973412-lvfeier-high-elastic-rf-emf-wifi-shielding-wool-thickening-cap) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
