Whether you're heading out for a run, managing heat sensitivity from MS, POTS, lupus, or menopause, or just need fast relief on a hot day, the ThermApparel Headband delivers targeted cooling right where it counts.

Worn across your forehead, it places our patented FlexCool66 cooling packs directly over blood vessels close to the surface of your skin. Just like a heat exchanger, the packs pull heat out of the blood flowing beneath them, and your body circulates that cooled blood back through your entire system, bringing your core temperature down from the inside out and cooling you head to toe.

Use it before activity to pre-cool, during to stay comfortable, and after to speed recovery. Pair it with your ThermApparel cooling vest for a complete head-to-toe cooling system.

About the Patented FlexCool66 Cooling Packs
The Headband uses our patented FlexCool66 cooling packs, a dual-sided design with a PCM side for cooling and a water side that keeps the pack soft, flexible, and comfortable against your skin. They freeze at 66°F (19°C), so they're cool and gentle, never painfully ice-cold. Important: do not place in the freezer. The water layer will freeze solid, making the pack stiff and uncomfortable. Recharge in ice water (20 min) or the fridge (60 min) to keep the skin-contact side liquid and perfectly shaped to your head. Learn more in our cooling pack guide.

Q: How does the Headband work?
The Headband places our patented FlexCool66 packs around your head, directly over blood vessels close to the surface of your skin. Think of it like a heat exchanger: the packs pull heat out of the blood flowing beneath them, and your body circulates that cooled blood back through your entire system, bringing your core temperature down from the inside out, fast.

Q: When should I use the Headband?
Before activity to pre-cool your body, during activity to maintain comfort, and after to speed recovery. It's also great as a standalone cooling tool for anyone managing heat sensitivity throughout the day.

Q: Can I use the Headband with my ThermApparel vest?
Absolutely. Your vest targets your torso and back, while the Headband targets your head, but together they cool your whole body from head to toe. Every ThermApparel product works with your body's own circulation to bring your core temperature down, so the more you layer them, the more effective your cooling becomes.

Q: Why can't I put the packs in the freezer?
The FlexCool66 packs have a water layer that keeps them soft and flexible against your skin. If you freeze them solid, that water layer freezes too, making the pack stiff and uncomfortable to wear. Always recharge in ice water (20 min) or the fridge (60 min) to keep them perfectly flexible.

Q: How long does cooling last, and how do I recharge?
Each set provides 30 minutes of cooling depending on conditions. Recharge in ice water in just 20 minutes or the fridge in 60 minutes. For longer sessions, keep a second set ready to swap.
