Yeah, they feel like a second skin, like you're not wearing anything at all. I usually just wear them around the house though, and if I do wear them outside it's with a long shirt. They're really not meant to be worn the same as regular pants/jeans and look best worn with a long shirt.
They really are that comfortable. I didn't want to wear them because they're the pants of the attention seeking whores but I bought a pair to workout in and oh my goodness they're comfortable. They're my new pajamas and my new workouts and my new I-don't-feel-like-putting-pants-on-today's.
Yes, yes they are. That being said, I don't usually wear them in public- the exception being if I'm running to the store early on a Sunday morning or I'm sick, but I have to go out for something (doctors, medicine etc.). The rest of the time, they're my at-home-and-feeling-lazy pants... I don't actually wear them for workouts- I usually wear shorts instead.
