"I went through 3 cheaper fans before this one. They all either broke, had no real airflow, or the battery died within an hour."

 Why you're still hot

Heat is getting worse. And what you've tried was never going to work.

550,000 people die from heat every year worldwide —
a number that grew 20% in the last decade alone.
(Lancet, 2025)

2025 was the 3rd hottest year ever recorded, with above-
average temperatures across 91% of the globe. No sign of stopping.

The real problem isn't your tolerance for heat. It's that handheld fans, cooling towels, and cheap clip-ons weren't designed around how your body actually overheats. They failed you because they were always going to.

  • 🤚 Handheld fan

    ✗ Occupies both hands. Useless the moment you try to actually do something.

  • 🧣Cooling towel

    ✗ Warm in 10 minutes. Then you're just wearing a wet cloth in the heat.

  • ❄️Portable AC

    ✗ Heavy, tethered to power, costs $350/mo to run. Not a solution.

     The real reason

    The Thermostat Neck Effect

    Your carotid arteries run within millimeters of your skin along the length of your neck. They supply 100% of the blood to your brain. When they overheat, they circulate warm blood through your entire body — raising your core temperature from the inside. That's why you feel completely overwhelmed by heat even in a mild breeze.

    No handheld fan targets this. No cooling towel sustains it. This does.

    How 360° Vascular Cooling works

    78 micro-vents wrap 360° around your neck, sitting directly over the carotid arteries and jugular veins

    Continuous airflow cools the blood before it circulates to your brain, organs, and limbs

    Your core temperature drops. Not just surface skin — your actual body temperature

    Research confirms: neck cooling reduces carotid arterial blood temperature by ~1.1°C and triggers reflexive artery dilation. Your neck really is your body's thermostat. (ClinicalTrials; AHA Stroke Journal)

      "This past week we had a heat index of 104°F and I work in a warehouse without AC or air flow. I'm usually sweating all day, but having air blowing on my neck really cooled me down. 100% worth the money."

      "Our temperatures in the desert are very hot — 112°F on weekends. I wear this every place I go. It makes it survivable. I couldn't survive without it."

      "Hollywood Studios — notorious for heat radiating off all that concrete — felt like an EasyBake oven. The neck fans were a godsend. We were able to enjoy the whole thing."

      BuzzFeed reviewer

       The real reason

      If heat is stopping you from living your life — this is for you.

      Outdoor & warehouse workers. When your employer won't fix the AC — take your cooling into your own hands.

      Menopausal women. An off-switch for hot flashes you wear around your neck. Discreet. Immediate.

      Hikers, cyclists & runners. Hands free for the whole trail, the whole race, the whole route.

      Families & travel. Disney in August. Concerts. BBQs. Finally enjoy the whole thing.

      Have Questions? We’ve Got Answers.

      We've heard every concern. Here's the truth.

      Will it tangle or pull my hair?

      The 100% bladeless design physically cannot cut or pull hair. No blades means no snagging mechanism — ever. It's also why it's safe for children and elderly users. Zero blades is a core design principle, not a marketing claim.

      At ≤25 dB, it operates below a quiet library. Reviewers consistently note they can hold full conversations, take calls, and hear clearly on all five speed settings. One verified buyer: "I have to ask the kids to speak up — but it is WORTH IT."

      On Speed 1: up to 16 hours. On Speed 3 (where most people run it): 7 hours. Speed 5: 3 hours. Honest numbers. One buyer was so confident in the battery they bought two units — "so I can charge one while wearing the other." USB-C charges both in under 2 hours.

      This is the right question to ask. It works because it targets your carotid arteries — not your face. Cooling the blood before it circulates drops your core temperature, not just the surface of your skin. Buyers in 104°F warehouses and 112°F desert heat confirm it. If you don't feel meaningfully cooler within 14 days, we'll refund you completely.

      30-Day "Actually Cooler" Guarantee

      Wear it to work. Wear it hiking. Wear it to your kid's summer tournament. If you don't feel meaningfully cooler within 30 days — you get a full refund. No hoops. No restocking fee. The only way this doesn't work for you is if you don't try it.

      Stop dreading summer. Start wearing your cool.

      63,229 people in warehouses, deserts, theme parks, and backyards already made the switch. The heat isn't going to get better on its own.
