Casual Box Neck Warmer Keeps you warm while HOT [Free Size/Brown] sleeping.

[A must-have item for winter chills] This neck warmer is made of soft, fluffy flannel fabric that you'll want to touch all the time. It has a smooth, silky feel and is lightweight yet warm and comfortable. Because it doesn't use electricity, it's the perfect cold-weather loungewear for saving energy in the winter. The secret to warmth is "HOT α": This neck cover uses "HOT α," a soft fabric with a moisture-wicking, heat-generating finish. The fibers absorb sweat and other moisture, generating heat and retaining heat, keeping you warm and reducing stuffiness and discomfort. A study of temperature changes after using the neck cover demonstrated a maximum temperature change of +2.4°C. [Convenient Design] This warmth is like a cozy blanket. It not only covers your neck, shoulders, and back, but also your nose when buttoned up, helping to prevent dryness. The elastic under the arms prevents the warmth from slipping off even when you roll over in your sleep, making it a comfortable shoulder warmer that's easy to move around in while doing housework. [Other Information] Our buyers, who have been working exclusively in the hat industry for over 20 years, oversee production, from materials to sewing, ensuring safe and reliable products.
