"I work outside in Phoenix heat and this thing is genuinely life-changing. The AI mode picks up when I start sweating harder and cranks up automatically. Wore it 8 hours straight on a job site."

"Hot flashes made summer unbearable. My daughter bought me this and I wear it every day. It's so quiet I forget it's on — and I finally sleep through the night with it on the nightstand fan setting."

"Bought 3 — one for running, one for my desk, one for travel. The battery indicator is clutch. The silver colorway looks premium, not like a gimmicky gadget. My coworkers all asked where to get one."

Everything you need to know.
How does the AI mode actually work? +
A precision thermistor sensor checks your skin temperature every 2 seconds. The onboard microprocessor compares your reading to ambient air temp and your personal baseline, then selects the optimal fan speed from 6 levels. As you cool down, it scales back to save battery. As you heat up, it responds immediately.
Is it really quiet enough for an office? +
At speeds 1-3 it runs at 25-32dB — quieter than a whispered conversation (40dB). Speed 6 at max reaches around 45dB. Most office users stay on AI mode which averages speeds 2-3 throughout the day. No one will hear it in meetings.
Will it mess up my hair? +
The airflow is directed forward toward your neck and chest, not upward. The fan intakes are positioned on the inner curve facing your neck. Thousands of customers with long hair report zero issues.
What's the return policy? +
Full 30-day no-questions-asked returns. If you don't feel cooler within 30 days, contact us and we'll send a prepaid return label and full refund within 2 business days. We also offer a 2-year warranty against defects.
Can I use it while exercising? +
Absolutely — the IPX4 sweat-proof rating handles splashing water, sweat, and light rain. The flexible neck arms adjust to fit while moving and the device sits snugly without bouncing during a run.
