I had bought a cheap article that I threw away. This time I paid more attention to the composition: Kevlar and Nomex exactly like those I had used and worn out in many years and I have bought with confidence. On arrival the result (heat resistance) is a bit disappointing and I am surprised to find no composition label on the article. Yet those who use the prestigious and expensive fibers generally indicate. I feel like I have made a lie of the composition. Of course the price of the item does not justify a claim or a return but I think that Amazon should be more vigilant vis-à-vis sellers on its site
