Protect your neck while running/biking :-)

This is a very nice thermal neck and, as the winter is right around the corner and I ride to work every day, this item is very useful. 

A very nice blue.

Very soft, skin pleasant material.

Therma-fit fleece fabric for warmth against the elements.

Contoured design for a pretty good fit and coverage.

 79% Nylon, 14% Spandex, 4% Rubber & 3% Polyester.

Use:

- cold and very cold weather, autumn, winter,

- by running, walking and biking,

- on the wild trail or for urban use.

Costs: 20 euros.

Very satisfied about it. I would have liked a red one, but the color options are pretty poor, only black, blue and mustard.
