I am not sure it works, but my deep sleep is improving on my Oura ring app. UODATE 2 weeks later, definitely sleeping better and found out it makes a pretty good sleep mask as well if you pull it over your eyes. I am a tinfoil convert.

Hi Steve, your Oura data is honestly the best kind of proof we could ask for. The effect is meant to be subtle, so keep an eye on those numbers over the next few weeks. Appreciate you giving it a fair shot.

Should have pulled out my tape measure to see the actual size of the blanket I was ordering. It looks like the size of a security blanket for a toddler. Not sure an adult can receive the benefits from the size that it is.

Hi Sydney, thanks for the honest feedback and sorry the size caught you off guard. If it's not working for you, we'd genuinely like to make it right, you're within our 30-day window, so reach out to our team (reply to your order email) and we'll sort out a return or find something that fits better. Appreciate you flagging it.

Site was simple enough for this TCP (Technology Challenged Person) to easily place an order and the product arrived in a timely manner. Only been using the beanie for a few days, so kinda early for me to evaluate it.
Response from HAVNJun 15, 2026
Glad the order was painless and arrived on time. We're here if you have any questions!

I like the baseball cap and beanie. I wish it weren't so expensive. But if they do help with the migraines I get, then they will be worth it. I get 45 days to decide, and I'm 2 weeks in, so we'll see.
Response from HAVNJun 15, 2026
Jennifer, thanks for the honest take — and that's fair on price; there's a lot of pure silver in these, so we know it's an investment. Really hoping they take the edge off your migraines.

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!

My brother ordered my beanie and it arrived within a week. Idk how it works or doesn’t work yet as i just opened it today. I saw another review saying they placed their phone inside the beanie and had no activity even though they asked a couple friends to contact them. I’m going to try it! If it even reduces some of the “brain fog” i’ll be happy with it. Let the experiment begin.
Response from HAVNDec 23, 2025
Hi there — thanks for sharing this, and for the thoughtful approach. Quick note on the phone test you mentioned: our beanies are designed to reduce EMF exposure to the head, not fully block cellular signal when a phone is placed inside. Signal strength depends on phone model, network, and surrounding environment, so that test can be misleading. The best way to assess impact is exactly what you’re doing now — with an EMF meter or real-world use over a few days, especially during sleep or long screen time. Many customers report clearer mornings, reduced brain fog, and more restful sleep over time. We’d genuinely love to hear how your experiment goes. Thanks again for giving HAVN a try and keeping an open, curious mind.

Good product if you are fortunate enough to receive it. I placed an order on April 10, 2024 for a beanie and a hoodie. I received the beanie but have as yet to receive the hoodie which was $349.00. (there was no mention of a back order or pre order when I placed the order for the hoodie) It's hard to get in touch with this co. or to get something other than a stock reply. I used to have a tracking number, then that disappeared now the tracking lists as "delivered", meaning the beanie, but no mention any longer of the hoodie for which I was charged $349. I wouldn't feel comfortable ordering from this company again. I'm editing my review because they did respond and said the hoodie would ship in 1-2 days and apologized for the misunderstanding that this was a pre-order and not in stock. I always look for that and did not see pre-order. At any rate, like I said, good product, just double check you are not ordering a back ordered or pre-order item if you don't want a long wait.
