Pleased with my purchase. The warm pair is not fuzzy inside, just thicker. This is great news if you hate pilling like I do. The fuzzy one get too rough for me after a season or two and then they're hand me downs or trash. The thickness of the fabric also makes them more supportive than the regular pairs, and disguises any texture you may have going on. Then regular pairs are thin feeling but not see-through, although if you have any deep crevices or larger bumps or dimples they will still show. For this reason, if you are between sizes, it worked for me to go down a size. I actually bought these for car rides. Every time we have family days I have an upset stomach by the end from my jeans digging into my gut. So I opted for the larger size, but I am right at the line between L and XL . The L is actually better looking on me and not much less comfortable. Only the top seem is sort of snug but I can just pull it up like Steve Urkle when I sit in the car and it doesn't bother me. The pairs with the white stitching are perfectly disguised as actual jeans in photos, without being so uncomfortable, but won't fool anyone in person if they look directly at them. Still, even the illusion on "real clothes" is better to me, now that I'm finding it hard to wear them.
