My HJC no frills XL full face helmet fogs up

[Possummanj]

I screwed a small plastic finger-(with just one small screw)-looks like a 2 inch popsicle stick -just under the visor --I can swivel it up to hold the visor open just a scoche--its enough to keep the fog at bay-or swivel it out of the way and let it snap closed.

I my HJC full face helmets will open a quarter inch to let air in but it's in the twenties F here in the mornings and I don't like that cold air on my face. These helmets vent up behind the shield from the chin area but that only helps a bit.

Update on the shield fogging; The trick to using a breath box is having it conform to your face. The HJC universal one has a bendable band in it, and it works fine in my HJC CL-SP helmet with no fogging at 30* F even when stopped.
