The reasons I bought this neck warmer are the following:
1) For me, fleece neck warmers are thick and don't stay on my nose or fit inside a full face helmet, making it difficult for me.
2) The balaclava, on one hand, raises the temperature on my head on not very cold days, and on the other hand, it's not convenient when I enter a store and have to take it off so I don't look like a thief.
This one from Cosa is not very thick, but it fits much better on the nose, slightly cuts the fog towards the visor, easily goes up and down, but it's not as warm on its own. However, it is convenient and serves me well (combined with a neck warmer under the helmet).

Very good fabric with great elasticity. Don't expect it to fully protect you from the wind and cold, but it does its job.

I have been using it for the past 4 months daily at work (delivery), it hasn't had the slightest issue and it does a great job with the frozen air, which is particularly unpleasant when it hits your neck and face.

Made in Greece, this product is made from high-quality bamboo material that prevents the cold air from reaching the neck and chin. I have had it for 2 years already and it has not worn out.
