Replying to Giro Shiv

Tried the search bar, could not find what I was looking for.

How well does the magnet goggle strap system work on the Shiv? Am I going to loose my goggles?

Normally I rock my goggles under my helmet and the Shiv seems like it is perfect for this. But on pow days, I hate wearing goggles under my helmet b/c of fogging issues thanks to the warm, wet, pow days we get here on the west coast.

Anyone ever have any issues with the magnet system?
