Wired for heating
Very comfortable and lightweight with an adjustable new type Velcro strap where the hook side is smoother and isn't clawing at my hair. The back side of the mask is a contoured memory foam that is very comfortable against the face as it doesn't push against my eyeballs, but still provides heat to the area.<br /><br />There are three levels of heating or if preferred, there is a gel pack that can be frozen for a cold mask instead. I prefer the heat function even though I have to be close to a power source and had to dig around for my USB extension to enjoy it on my bed.
