Refresh your ThermApparel Headband with a new set of patented FlexCool66 cooling packs.

These lightweight Headband cooling packs freeze at 66°F (19°C) for safe, gentle skin contact.

Think of it like a heat exchanger: placed across your head, the packs pull heat out of the blood flowing through vessels close to the surface of your skin, and your body circulates that cooled blood back through your entire system, bringing your core temperature down from the inside out. They provide dry, comfortable cooling that won't soak your hair or drip down your face.

This package includes:

2 patented FlexCool66 Headband Cooling Packs

Key Features

• Patented FlexCool66 technology freezes at 66°F (19°C) for comfortable, skin-safe cooling (not ice-cold)
• Dual-sided design: PCM side for cooling, water side keeps the pack soft, flexible, and easy to shape around your head
• Designed to recharge in ice water or the refrigerator so the skin-contact side stays liquid and flexible
• Works in both humid and dry conditions for reliable cooling almost anywhere
• ThermApparel's bio-based PCM is non-toxic and biodegradable, offering a more eco-conscious cooling solution
• Fast refreeze times: about 20 minutes in ice water or 60 minutes in the fridge
• Reusable thousands of times with proper care

NOTE: Do not refreeze in the freezer. The water layer will freeze solid, making the pack stiff and uncomfortable against your skin.
