The coyote hunt crew I night hunt with recently added a Pvs14 to the arsenal.
While on the helmet it tends to fog up.
What do you guys do to mitigate this condesation build up that seeming gets trapped in
the eye cup/ lens?

Is there a particular brand of anti fog wipe ?
 
FOG TECH

But also, putting the optics in the garage for 30m before heading out seems to help.

Oh and I remove the eyecup.
