I found this item while looking for a sweat cap as the seller clearly thought it would be suitable for the purpose. It's 87% polyester, which means an accidental spark will go right through it and melt the thing on my head. To top it off, the product image isn't even the same hat because it appears to be about 2 or 3 times thicker than what came in the post, which as I said above is about as massive as a Pair of tights. Do not buy.
