Endorsed by 200+ clinicians, including neurologists and surgeons, our products are recommended to patients for better health.With 5.5 billion people globally reliant on cell phones and other wireless devices, EMF radiation has become an inescapable part of everyday modern life. In fact, over 2,200 scientific studies have linked EMF exposure to significant long-term health risks, including cancer, fertility issues, and neurological disorders. Leading health organizations worldwide, including the NIH, WHO, NCI, and EPA, are raising the alarm about the dangers of EMF exposure.Leading health organizations worldwide, including the NIH, WHO, NCI, and EPA, are raising the alarm about the dangers of EMF exposure.Prolonged EMF exposure poses risks to cancer, reproductive, and cognitive health. A $30 million study revealed significant DNA damage from EMFs, a key cancer precursor, and the WHO classifies them as a class 2B carcinogen. EMFs also harm reproductive health, lowering sperm count and motility, while studies link them to memory problems, poor sleep, and chronic fatigue.Exposure to EMFs from personal devices, Wi-Fi routers, cell towers, and smart home technology is rising, and awareness of their health risks is growing. As more people recognize the potential impacts of everyday tech, protecting against EMFs has become a priority for health-conscious consumers.HAVN created the world’s first EMF-blocking clothing for everyday wear. Inspired by spacesuit technology, our proprietary WaveStopper™ fabric uses pure silver fibers to create a conductive barrier and block over 99% of harmful EMFs from ever reaching the body. With years of development, millions of dollars invested in R&D, and 12 patents filed to protect the innovation, WaveStopper™ is the only scientifically proven solution to conveniently block EMF in everyday life. The technology’s efficiency has been tested and certificated by independent military-grade Eurofins MET Labs, ensuring its reliability and effectiveness according to top IEEE-299 and EN62209-2 standards. From beanies to shirts and underwear, each HAVN product line shields vital areas like the brain, chest, and reproductive organs. HAVN garments offer comprehensive protection, shielding you from EMF radiation, blocking 99.5% of UV rays, and naturally providing antimicrobial and odor-resistant properties.

They can maintain their effectiveness through more than 300 washes.We hold an unparalleled position in the market as the first and only brand with EMF-protective apparel scientifically proven to protect long-term health and well-being from the impact of EMF exposure. Our customers rave about the peace of mind of using technology while knowing their health and that of their family are protected.In addition to supporting long-term health, shielding from EMF also has numerous science-backed benefits on well-being. EMF exposure can increase cellular and oxidative stress, impacting cognition, sleep, brain fog, immunity, and accelerated aging.The real-life benefits of HAVN have been highlighted by independent pre-studies. A 2020 pre-study showed that wearing HAVN when exposed to EMF radiation improved HRV - an indicator of the body’s stress level - by an average of 18%. In 2023, an independent study from the Aspen Neuro Institute used EEG technology to monitor brainwave activity in individuals exposed to EMF radiation from idle smartphones near the head. The results showed a significant reduction in brain stress when wearing HAVN headwear.The benefits of wearing HAVN have been consistently by our polled customers throughout several years:Our customers are our best advocates, and their feedback speaks volumes.

Thank you for your continued support and for being an investor through Republic—it means a lot to us!

Also, I have not seen any posts since July 2025. What is going on with the company? Thank you. - Q: Q4 Update? - Q: I haven't seen or heard from you gusy in awhile? - Q: I have a few items. Are there any plans to use natural (and organic) fabric(s) vs. synthetic? Since Lambs/HAVN is into frequencies - it is kind of disappointing that synthetic (petroleum based) fabric is used. - A: Hi Kathleen, Great question! We’ve been testing organic yarn options for our fabric for a while now, and we’re excited to share that we’ve validated a new version of our WaveStopper™ fabric incorporating organic cotton. This new material meets our high standards for EMF protection, comfort, and durability, and we’ll be using it in our next productions. Stay tuned for more updates—we can’t wait to bring this to our community! - Q: Hi, I have bought several HAVN products (as far back as when the company was called Spartan), but the market for RF-resistant clothing is still fairly niche. What is HAVN doing to expand that market? Are efforts underway to bring down the cost? What about expansion into other RF-blocking products (Faraday bags, etc)? I'm very interested in investing but would like to see how the company plans to grow its base. Andy - A: Hi Andy, Apologies for the delay in replying—I missed the question section on Wefunder. Thank you for your support over the years—it’s incredible to have customers who’ve been with us since our Spartan days! You’re absolutely right that the market for EMF-blocking clothing is emerging but rapidly growing. With over 50% of Americans believing EMFs are harmful and 20% actively seeking ways to reduce exposure, awareness surrounding EMF-related health risks is already on the rise—and we’re working hard to expand it further. 1. Expanding Awareness and Education We’re focused on building awareness of EMF exposure and its potential health impacts, which is key to expanding the market. This includes educational campaigns, partnerships with doctors, endorsements from athletes like Rudy Gobert, and tapping into broader conversations about health and wellness. With HSA/FSA approval, we’re also making it easier for customers to adopt our products as part of their healthcare routines. 2. Making Products More Accessible Right now, our focus is on maintaining the highest quality for our products, which is essential given the advanced technology and materials we use. However, as we scale, we’ll have more opportunities to optimize our supply chain and manufacturing processes, which will allow us to bring costs down and make our products more accessible to a wider audience. 3. Broadening Product Offerings We’re currently only at 3% of our total potential offering. Our proprietary WaveStopper™ technology has immense potential for expansion into additional product categories, all while staying true to our mission of providing effective, science-backed solutions for reducing EMF exposure. This is an area we’re actively developing, and we’re excited about the opportunities ahead. 4. Scaling for Growth Our strategic plans include growing into 9-figure revenue territory within the next five years by expanding our SKUs, increasing B2B partnerships, and leveraging traction with the military and healthcare professionals. We’re also seeing strong traction internationally, which offers significant growth potential in the future. We believe that as more people become aware of the benefits of RF protection and experience the impact of our products, the market will continue to grow. Your interest in investing means a lot to us.
