only the outside of the scope, it cleared pretty quick after i shot it, who knows, maybe it was all my hot air from me hyperventelating the entire time saying "holly ...." over and over about 3000 times in about 21 seconds. After the hunt, i realized how important anti fog is.... I shoulda known better, i use it on my dive masks, and it works, but crap, I didn't expect to shoot a deer honestly, I've spent hundreds of days in the woods chasin deer and never shot a buck so I figured it would be about the same day
