I suffer from neck pain often, which is why I wanted to try this scarf. the warmth gives relief, both during acute pain, but also sometimes to prevent it..
This scarf is short and narrow. it covers just enough of the neck, and the part that warms is a small central portion.
the package also has its own pouch for convenient storage and carrying, and a lightweight powerbank.
at the ends, on one side there is a kind of internal bag in which there is the usb cable to charge it. you can charge it with a normal usb outlet, or with the powerbank.
It 'closed on itself and allows you to fit the other end, so as to tie around the neck the scarf.
I find it very convenient, because you can use it around or at least not being attached to the power (by the way I do not think you could keep it attached to the power).

Excellent product. Lightweight at the neck, soft and with three intensities of heat. Convenient and comfortable both indoors and out. I am very satisfied with it.

Keeps well warm and is soft

I use it on the farm in the winter it is cold working with animals

The product is perfect just not enough for the use it was intended for the heating zone is too limited, but this is a limitation in my case not a criticism of the product.
