You take it off because it gets heavy. Not this one.
Most cooling gadgets work brilliantly for twenty minutes and then you notice them. The weight on your shoulders, the battery warning, the buzzing in your ear. AeroFrost Halo weighs less than a can of drink, runs for fifteen hours and makes almost no sound. You put it on in the morning and you forget it is there until you take it off at night.

The feeling of ice, without the ice.
The plate resting on the back of your neck is not a fan. It is a thermoelectric cooler, the same principle used in portable fridges, and it pulls the temperature down by 11 to 16 degrees the moment it touches your skin. Combine that with air moving up and down around you and the heat simply stops reaching you.

Fifteen hours. Twenty-eight decibels. Zero effort.


Up to 15H Battery
≤28dB Brushless Motor

Everything you need to know.
Does it really cool, or does it just blow air?
Both, and that is the point. The turbine moves air around you in 360 degrees, and separately a thermoelectric plate sits against the back of your neck and physically drops the surface temperature by 11 to 16 degrees. The airflow keeps you dry, the plate keeps you cool.
How long does the battery actually last?
The 4000mAh battery gives up to 15 hours on the lowest fan setting. Running the cooling plate alongside the fan draws considerably more power, so expect a few hours in that mode rather than a full day. A complete recharge takes around four hours over USB.
Is it loud? Can I wear it around other people?
It runs at 28dB or below, which is quieter than someone speaking softly across a room. The brushless motor produces almost no vibration, so you can wear it on a call, in an office or on a train without anyone noticing.
Will it catch my hair?
No. The blades sit fully recessed inside the housing with no exposed opening wide enough for hair to reach. Long hair, necklaces and collars stay clear of the mechanism.
Will it fit me, and is it heavy after a few hours?
The silicone band flexes to any neck width, so there is only one size and it fits everyone. At 356 grams it is light enough that it rests on your collarbones instead of pulling on your neck, which is why people wear it all day without soreness.

The one people actually keep wearing.
"I was pretty hesitant to buy this because I work in a fairly quiet open-plan office, and I was terrified it would sound like a hair dryer or annoy my coworkers on Zoom calls. Total surprise: on speed 1, you can barely hear it running. The plate on the back of your neck gets ice-cold the second you turn it on—it doesn't just blow hot ambient air around like those cheap $10 fans. I keep it at my desk all day now."
"Last summer I bought a cheap plastic neck fan on Amazon and ended up throwing it in a drawer after three days because it felt so heavy and gave me shoulder ache. You can feel the quality difference with this one immediately: the flexible silicone band fits comfortably without squeezing, and the weight sits balanced across your collarbones. I use it for my daily tube commute, and it is honestly the only reason I don't arrive at work with a soaked shirt."
"I have hair down past my waist, so my first thought was: 'my hair is going to get sucked into this instantly.' Not at all. The air intakes are completely enclosed with zero exposed blades, so you can move around without worrying. The little side screen that shows your exact battery level is super handy so you never run out unexpectedly."
"Bought this for a trip to Florida in brutal humidity. I was a bit worried about battery life, but it lasted me through almost the entire day using it on medium speed on and off. Running the cold plate constantly drains it a bit faster, but plugging it into a USB-C power bank tops it up in no time. Literally saved my vacation."
"In Southern Europe at 38°C (100°F) in August, a standard fan just blasts hot hairdryer air at your face. The game-changer here is the metal cooling plate on the back of your neck: it delivers an instant icy sensation that cools down your whole body. It won't turn the outdoors into a air-conditioned mall, but it completely removes that sticky, suffocating heat feeling."
"The build quality and matte white finish look much more like an Apple product than a summer gimmick. A cool little feature I didn't expect to use is the built-in night light. It's super convenient for biking home at night for a bit of extra visibility. Really happy with the purchase."
