I've just spent 7 hours MIG welding, acetylene heat bending, grinding and grinding steel with these gloves and they couldn't be better. Really high quality materials. I accidentally grabbed a piece of very hot steel and the glove smoked a bit, but the heat didn't transfer to my skin and the smoking part was completely intact. The inside is soft and comfortable. The only thing I don't like is that when you take off the gloves, the balaclava crumbles a bit, leaving small lint on the hand. But it doesn't matter. The dexterity is excellent, I can use my fingers easily in these gloves. It immediately got dirty outside as they are white but that was to be expected. In general, they are very high quality, especially considering the price. I definitely recommend them.
