Just mentioned this in another post on the forum but the Empire E-Flex were perfect for me, nice fit not squashing the head, plenty of lens room and the bottom half of the mask is no where near my face and it has plenty of "holes" for breathability to stop my glasses fogging.
I did find the VForce profilers were actually a close second in terms of fit, they only lost out as I found the E-Flex breathes better.
