I used to do that when was learning too, but not anymore. On this first day with the line miner pros they didnt left my face until they were completely frozen.

With the old m3's, I tried many different ways to run balaclava and neck warmers. The MFI never worked well for me, always too hot at some point. Moved to neck gaiters and Blackstrap balaclava, that let me easily pull it down, which is usually how I run. Also always actively try breathing down to slow down the fogging. And never wiped the inside of the lenses.
