I've got a buddy that bought into the whole "Technically" they're required at all times line of thinking and wasn't wearing his gloves when his Phrog was shot down. As fire started to consume the aircraft (and they were in the process of landing), his hands got severly burned. He wears gloves all the time now.
I hear you. As long as you know that going in and are cool with it, I think it's up to the individual to decide (unless the Boss is watching). It's not even something that the NATOPS Es in my community emphasize.
