Just... wow
I honestly didn't even realize the "thermal" element of these when I bought them (sometimes my attention to detail isn't the best lol), and I'm glad, because I probably wouldn't have bought them if I had because I tend to run warm. But I wore them anyway this week even though I'm in Texas and it's hotter than average for May. The good thing is that they aren't actually less breathable than usual — no higher poly content or such — it's just that they are "brushed" on the inside of the fabric, and man does that make them soft and cozy.
But my favorite thing about them is that they DON'T BAG OUT. I'm plus sized, and pretty much any jeans end up losing shape after a day of wearing, regardless of how fitted they are, whether there's spandex, etc. So that pretty much makes them a miracle, and they immediately became my favorite jeans in my closet.
