So now that we've had a chance to play with these masks a little, I have to say I really like it a lot. Though I have to agree with what Bill was saying the other night about it not really protecting the adam's apple on the throat. The metal armor discs that are riveted into the bib still allow a lot of flex here.
Of course, you can still wear a gorget. I was tempted to include one of Terry T's gorgets in the order with the mask, but I don't know if they're any more protective than the brigandine style gorget I already have. I'd be curious to see if they're made with the same design as the bib on the masks.
Still, overall the mask is well built, sturdy, fits nicely, and is adjustable.
