Hi Christine, your order is on its way and should be delivered today. We hope you love the products! If you get a chance, we'd really appreciate you updating your review once you've had the chance to try them.

I used an instrument called a gaussmeter to measure how much EMF my HAVN cap/beanie cut out. It had no effect. That HAVN beanie may have some placebo effect, but it does not block EMF.
Response from HAVNApr 15, 2026
Hi Anne, thank you for putting our beanie to the test! We genuinely appreciate customers who dig into the science. One important note: a gaussmeter measures static magnetic fields, not the RF/EMF frequencies our WaveStopper fabric is engineered to block (think cellular, Wi-Fi, and Bluetooth frequencies in the MHz–GHz range). For accurate results, you'd need an RF meter: we're happy to point you to specific models we recommend, as well as independent customer tests on YouTube and Instagram where others have verified the shielding performance. Feel free to reach out to us directly and we'll send everything your way. We stand fully behind our technology.

High quality clothing that will get you flagged EVERY TIME you go through a TSA scanner. I bought these for flying but stopped using them because i got tired of being molested at the airport every time i fly.
Response from HAVNApr 15, 2026
If the TSA scanner is flagging you, the silver is doing exactly what it's supposed to. That said, we completely understand the friction, nobody wants extra pat-downs on every trip. A few customers swear by packing their HAVN pieces in carry-on rather than wearing them through security. Might be worth a try!

Horrible customer service. Here is an email that I sent them and I have gotten zero communication back. "I have, over the past several days, emailed, on multiple occasions to get an update on your shipping courier's mistake, where they delivered my order to the wrong house. There is a whole string of emails dating back over a month ago. And I am very upset over the lack of communication and customer care. I did not receive the product I ordered in November 2025 and the Proof Of Delivery pictures that HAVN sent me from the courier are not my house or my street. I am a repeat and previously satisfied customer who is now being ignored by HAVN. So I am now reaching out to this email address in an effort to get a swift resolution to this problem and possibly save your relationship with me. I am looking forward to your reply on Monday, March 9, 2026."

We sincerely apologize for this experience. A misdelivered order and delayed communication is not the standard we hold ourselves to, especially for a returning customer. We've escalated this internally and want to resolve it as quickly as possible. Please DM us your order number if you haven't already, and we'll make this right.

Poor communication. Item is not as decribed and does not block anything after multiple tests with multiple items. I'd avoid the company and these products.
Response from HAVNMar 18, 2026
We're sorry to hear this. Our WaveStopper fabric is independently certified by MET Labs to block up to 99% of EMF radiation, and results can be verified with a standard EMF meter. We'd like to understand what you tested and how — different testing methods can produce different readings.

I have just ordered with this company and of course I have done things in reverse. I have looked at the reviews after placing my order and these things I’m not cheap. I have ordered two beanies. That was today Monday, the 2nd of March I’ll keep you posted  UPDATE 3/5/26 my beanies have arrived and they are beautifully engineered soft and comfortable. I slept in one last night, because I sleep with my phone really nearby because of my children and it was comfortable and cool, and I believe it does prohibit to some extent the exposure to harmful radiation. I’m glad I ordered and thank you HAVN!!

Do not waste your money with them. They do not care about their customers. Purchased two items that weren’t shipped in the timeline they promised, then when I inquired, they said it shipped suddenly, but it was too late because I left that property and could not retrieve my package. So I lost $140. Re: Their response below is a complete lie. I never heard anything from them except "SORRY, your problem not ours!" Essentially they were unwilling to do anything about the issue. Also, the items were not noted as backordered at checkout, but an email was sent with an expected ship date. Nearly three weeks past their expected ship date went by before it was shipped, which was literally two days after I inquired. Coincidence? BE VERY CAREFUL doing business with these people.
Response from HAVNMar 4, 2026
We're sorry about your experience. The items you ordered were on backorder, which was noted at checkout and in your confirmation email with the estimated ship date. Our records show we reached out twice to help resolve this but did not hear back. We'd still like to find a solution — please Email us your order number so we can look into this for you.

My order placed 1/30/26. After reaching out almost 2 weeks after, they followed up email stating my 3 were shipping and the order would update with tracking. It is now 2/17/26 and nothing updated or shipped still, no package and now zero updates or reply / response from the company. My order info also disappeared from SHOP and I find that very odd. I am following up with my credit card company today and filing a claim. Also with as many online review sites as ive seen with the same issue I and going to cancel the order and file a dispute. Buyer Beware !
Response from HAVNMar 4, 2026
We understand your frustration. The backorder timeline was noted on the website at checkout and in your confirmation email. That said, we want to confirm that all backorder items have since been shipped and received by customers. Please DM us your order number so we can verify the status of your specific order and resolve this directly.
