Heated Scarf, Warm Up to Cold Weather with the Thaw Heated Scarf. You might be wondering why you'd need a heated scarf when you have a regular one or a built in collar on your coat. Allow me to explain and you'll wonder why you didn't think of this sooner. The Thaw Heated Scarf was purposefully designed to deliver rapid warmth and superior comfort in cold conditions more effectively than the average scarf or collar on a coat. Much like the cooling effect of an ice pack on the neck during hot weather, our scarf optimally targets this same area with heat in cold weather conditions for a soothing warming effect. The reason this works is because the brainstem resides in this part of the neck, and it is responsible for helping you to sense and regulate your body temperature. Powered with an included 5000mAh power bank, the scarf has 3 heat modes reaching up to 131F/55C and a max run time of 21 hours, so you'll be able to dial in your comfort level and adapt to changing environments without having to take a break from the cold. The fleece liner is comfortable against your skin while the down insulates and the exterior nylon shell provides wind and water resistance. The interlocking design keeps the scarf perfectly in place, and easily adjusts to accommodate all sizes. Experience the ultimate cold weather companion that not only shields you from the icy wind but also taps into your body's natural warmth mechanisms for maximum coziness.
