Another consideration for those who feel pressure on the forehead later in a session. Check your balaclava.

Good point Chris. With my Sport, I wore a balaclava that was carbon/kevlar blend--it was very thin without the vertical seam on the forehead--it made the helmet bearable for most of a session. My prior balaclava had a veritcal seam in the forehead that was the cause of most of the discomfort.

The Pyrotect really lacks adequate padding in the forehead area and my balaclava is a Carbon-X model without seams in the forehead area.

Try the helmet on with the balaclava on you intend to wear. If it is uncomfortable in 5 minutes, it most certainly will be in 30. Lastly, unless you are fortunate enough to have a head that fits a S/M/L/XL helmet well you might want to go with a model that offers hat sizes. I usually wear a 7 1/8, with some models that makes a pretty darn/too tight small or a way too big medium.
