Of course it is nicer and recommended that soft fur coat to the skin, the result will be even faster and more efficient! or wear it on a lightweight garment, it seems to me it is pure and simple logic!
For those damp winter weather it is nice to take a few moments this neck warmer or after a tiring day or cold, or before going out, to feel warm already and ready to face the wintry weather! In any occasion, anytime, twists torticollis, rheumatism, small headaches or shoulder, that is the surest antidote to feeling good in no time. I recommend, of course!
