CarHartts FR clothing is what I look for when looking for the protection and comfort ability to work in a safely manner.
I give The FR lightweight twill a 5 star review because of my experience with CarHartt FR Clothing, working as an electrician I find that the shirts and pants are comfortable enough to let me work in a safely manner, the FR protection has proven to work every time, it is everything I look for when using FR clothing.
This is a nice looking, durable, and comfortable FR shirt. I have experienced the same static cling problem that another reviewer had. The other Carhartt FR shirts that I wear do not have this problem. You might need to look into the material used for this shirt.
