Sure, these thermals are warm. They're also extremely high-waisted and the crotch on mine ripped a huge hole within the first month I wore them. I live in California, and I bought them just to sit around the house in, so I didn't even give these leggings too much wear before the crotch gave out completely. Right now, there's a hole large enough to stick a couple of fingers in right where the two seams cross at the crotch.

To clarify, the SEAMS THEMSELVES didn't rip. The FABRIC ripped OFF OF THE SEAM. wtf.

My boyfriend also makes fun of me because they're as high waisted as a pair of control-top pantyhose.

Do you want to look like you're wearing crotchless mom jeans? Then go ahead and buy these thermals.
