Fogging up of Panoptx goggles

[20/20_Hindsight]

Anyone have trouble with Panoptx goggles fogging? I own about 6 pairs, but one in particular always gets fogged up. Is it safe to use anti-fogging spray on them? I know I should contact Panoptx directly to ask, but wondered if anyone had this problem and found a solution.

Thanks

I've tried several models of Panoptx. I ended up sticking with the ones that don't fog (for me, Sirocco and Raptor). I concluded fogging has to do with the fit of the frame. Panoptx' frames are rather 'face-specific' in this regard.
