Although they are considered full seal I would not recommend them at all. It is because they are fully sealed that there is an issue. They are a single pane lense (no thermal break like dual pane) and because they are fully sealed they have no air movement between the lense and face. I had a pair of sg1's and had to remove 80% of the foam so they wouldnt fog. Even with the foam out I would fog them up very badly in high activity or rain. I tried all types of anti fog on them and none really worked.
