Nothing about it announces itself: no logos shouting shielding, no stiff panels, no tech-store styling. It is the emf protection cap you can wear into an office, a classroom or an airport without a single question, and the rear strap means one size genuinely covers most adult heads. WHY A CAP RATHER THAN A BEANIE A 100% cotton shell breathes in summer where knit cannot, the brim shades your eyes outdoors, and the adjustable closure suits anyone between hat sizes. If you want a faraday cap for daytime and warm weather rather than a winter beanie, this is the one. WHAT IS INSIDE WaveStopper is a silver-fiber mesh woven into a soft inner layer. Silver conducts, so the mesh spreads and reflects incoming wireless energy instead of letting it pass through the fabric. The construction is lab-tested to IEEE-299 and EN 62209-2 and blocks up to 99% of wifi 5G cellphone and bluetooth radiation across the frequencies your devices actually use. WHO BUYS IT People who work surrounded by routers and laptops. Frequent flyers. Anyone in a dense apartment block ringed by neighbouring wifi. Parents who want shielded headwear for themselves before anything else. If you have been searching for emf protection clothing rather than another gadget, this is the wearable end of that category. HOW TO LOOK AFTER IT Wash cold and gentle, never hot, and skip bleach and fabric softener - both attack silver fiber. Air dry. Looked after properly the shielding layer keeps performing for years of regular wear. WHY HAVN HAVN builds shielding into clothes people would wear anyway. Certified fabric, honest specifications, no novelty-store shortcuts. One size unisex ## Features - BLOCKS 99% OF EMF RADIATION: this EMF blocking hat is lined with patented WaveStopper silver-fiber shielding lab-tested to IEEE-299 and EN 62209-2 so wifi 5G cellphone and bluetooth signals are attenuated before they reach your head. - ADJUSTABLE FARADAY CAP FOR EVERY HEAD: a rear strap dials the fit in for men and women and the 100% cotton outer shell stays breathable through summer while the brim adds shade on bright days. - READS AS A NORMAL BASEBALL CAP: no visible shielding and no tech-looking panels - a plain black silhouette that carries an EMF protection cap into an office a flight or a school run without comment. - ONE SIZE UNISEX FIT IN BLACK: the strap covers most adult sizes - hand wash cold and air dry to keep the silver lining performing exactly as it did on day one. - PART OF THE HAVN EMF PROTECTION RANGE: add our lightweight EMF beanie for sleep or our knit beanie for winter and keep shielded headwear in rotation all year. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D9J3J66M | | ASIN | B0D9J3J66M | | Age Range Description | Adult | | Apparel Fabric Stretch | No Stretch | | Apparel Fabric Weight Class | Medium Weight | | Brand Name | Lambs | | Closure Type | Snap | | Colour | Black | | Customer Reviews | 4.0 4.0 out of 5 stars (38) | | Customer reviews | 4.0 4.0 out of 5 stars (38) | | Date First Available | 4 Oct. 2024 | | Department | Unisex | | Fabric Type | WaveStopper™ inner layer: 100% pure silver fibers.
