I'm a sweats and socks guy. That, for me, is comfort. I suppose if it were comfortable for me I'd go w/o clothes, but it genuinely isn't. It would make me feel, well, naked...
This article really surprises me. I thought everybody felt uncomfortable w/o clothes.
Who knows, the survey may have been taken in CA which means all bets are off. LOL
I would figure most people would work in sweats or shorts. I like gym shorts myself.
Heck, if you're gonna be working out of home, may as well be as comfortable as possible, eh.
