Solid Go To
I ordered a few products from HAVN, initially I thought this wouldn't be the product I ended up liking the best but it surprisingly has become my go to. I love sleeping in this, using it for runs and just wearing it out and about. It can be a bit snug but snug is good when you're primarily buying this for EMF protection. Just be aware your face is still always exposed to the radiation even if you wear the hat.

Sleeping well / product suggestion
I can’t believe how well I’m sleeping since I received my beanie. Product suggestion: I have several ball caps that I like to wear. How about designing a ballcap insert of your silver lined fabric with Velcro tabs to attach inside three or four hats so it can be switched from hat to hat. I would buy three or four of these, and I would gladly help you test market them.

Love it!
I love this beanie! It’s a snug fit but not too snug & I like that because it stays on throughout the night. Washes up nicely, too. Very soft.
