58° Chill -The Opal Cool Cap and Opal Cool Eye Mask maintains a comfortable, soothing 58° F temperature for 20-40 minutes, depending on ambient temperature. Cool in the refrigerator or in a cooler for 30 minutes to reactivate.

Scientific studies suggest 58° F is the optimal cooling temperature for safe, effective cool therapy. Opal Cool’s PCM stays comfortably cool without the known risks of using ice-based products: skin burns, frostbite, tissue and nerve damage.

Lifestyle: the Opal Cool Cap’s design to fit under hats makes it a convenient head cooling option not only at home, but also while doing outdoor activities such as gardening or barbecuing, and packs well in a cooler for head cooling relief at festivals, sports games, and more
Heat Stress Relief: head cooling helps mitigate heat stress and fatigue
Headaches and Migraines: helps relieve stress and tension
Dark Circles and Tired Puffy Eyes: helps minimize the appearance of dark circles and puffiness under the eye

Opal Cool products are made with plant-based cooling PCM that is specially formulated to provide cooling relief at just the right temperature.

Unlike ice packs or gel-based coolers that start uncomfortably cold and then warm up quickly, Opal Cool’s PCM products maintain a consistent, comfortable cooling temperature. Even better – you can wear these directly on your skin.

When Opal Cool’s PCM comes in direct contact with your skin, the cooling pods gradually pull heat away from your body, which causes them to slowly melt and change from a solid to liquid. When the pods are completely clear, it’s time to remove and recool your mask. Great news: you can reactivate and reuse these over and over again!

Worry-free cooling: You can recharge these in the fridge or freezer. When you place it on your skin the PCM quickly self-regulates to its skin-safe temp.

Safe, long-lasting, and comfortable cooling. NO RISK OF ICE BURN OR FROST BITE – so much nicer than ice~
