Lambs HAVN EMF-Proof Cap - Wavestopper™ Silver Tech - Blocks 99% of EMF from WiFi, 5G, Phones, Bluetooth - Faraday Hat, Soft, Breathable, Adjustable - Black, Unisex Design for All-Day Comfort.

I did some research into the different brands for getting EMF blocking clothes, and I chose the HAVN hat because it seemed the most legitimate, and very high-quality. After wearing the hat for the past two weeks, I’ve been very impressed with the quality. Considering the material costs as much as cashmere to produce, the price made sense and it’s worth it to know that it truly works. It’s very comfortable and well made. It fits well. I like the style, It’s very clean. and I truly believe the functionality is superior to other brands. I will definitely be buying more HAVN gear in the future.

LOVE the HAVN/lambs clothing! I have tested them with an EMF tester, and they are legit. I have also worn the shirt for 2 weeks and tested HRV with a shocking improvement noted. As a clinician, this means health improvement is possible. The hat is especially comfortable as is the clothing line. Be good to your health, purchase, and notice/feel the difference.

I love this cap. It fits really well, feels comfortable, and gives me peace of mind knowing it’s helping block EMF waves. Simple, stylish, and exactly what I was looking for. The fit is perfect and it is adjustable.

Bummed it was cheaply made. I hope they will make them well someday.

Big fan of Lambs/HAVN products. This is a solid cap, seems well constructed, and I like the minimal design (all black with just a light 'Lambs' on the back). Love that I can stay protected from EMF, especially here in TX where it's getting too hot for the beanie. Helps me stay clear-headed and focused during the day.

I’ve been wearing this product consistently for well over a month. It’s not as breathable as it claims to be. It is a comfortable hat, but even with regular hand washing it has faded in color partly from my heavy sweating on hot days. I’m not pleased with how it looks now. I’ll be replacing for a regular hat to capture sweat and the hard load in and out days at work.

Looks: sharp hat that looks and fits great in both casual and semi-casual settings. Have received many compliments. Friends are even more impressed when I then tell them about it's function... Function: absolutely works as designed. I have sensitivity to EMF (headaches, dizziness, minor tinnitus). During a long work-day in front of multiple laptops and cell phone, I often find symptoms flare up. I now put on the hat and see my symptoms decrease in a matter of seconds. Truly amazing. Really makes me wonder how many other people are effected similarly, and could benefit from this type of protection. I also recommend HAVN's shirts. I've been wearing them for 2 years and noticed a significant improvement in health and recovery from workouts. The most obvious benefit for me was distinct and lasting decrease in my resting heart rate to a much healthier level.

Love this cap! It is seriously the most comfortable cap I have, and protects my head from RF and EF from home wifi quite well! Well worth it!
