what anti fog are you using? none that i have tried have worked. rain x anti fog worked for a short time.... maybe 10 minutes. but then again if i can keep from breathing hard ( or yes rolling
) i can keep it from fogging that long also.
I think fogging is just part of kayaking in the early spring, Fall and winter.... there is just to large of a temp. variance between the cold water/near freezing air temp and your face putting off all that heat.
I may break down and try the contacts.
Saturday while running laps on lower narrows i fogged the entire time on the river....but would clear up on the hike back up. go figure .
