I have two sets each of 80cm warm underwear. I think we can get through the winter with the bare minimum. The star and fox patterned ones are like quilted material and look very warm, and I loved them because they feel good on the skin! Also, they open in the front, so they're easy to change when there's a poop leak, which I recommend♪ The two in the second photo say they are not quilted but are made of warm material. I don't think there are any noticeable stains, but please understand that these are used items.
