## Questions & Answers

**Q: Is this all that you see or just the top half?**
A: It is the entire balaclava. But please note: per the seller, Abolox Safety, this description is incorrect. Not only is it the entire balaclava, it is not FR rated. I'm returning the one I just received as my situation requires fire retardant.

**Q: where is this product made in ?**
A: Thank you for your question. This is made in China.

**Q: Is this FR rated or not? I must have FR for work.**
A: It says on the packaging that it is FR until you put it through a washing machine. It is FR coated I guess not Nome material.
