These are some old school 2xist briefs. I don’t even remember what line they are from anymore, and I know that 2xist doesn’t make them anymore. I wish that they did. These are some of the most comfortable undies I have ever owned – and coming from me, that should tell you something. These were from a green line that 2xist did – organic and sustainable fibres. I think these are made of soy. They are super soft…super comfortable and they feel so amazing on. I can’t even begin to describe to you what they feel like on. They hug every little curve and caress your body. I don’t know what it was that made me put them on this morning. I opened the drawer and pawed around a bit and these popped up, like they have a few times before, and I thought I would be passing on them again, but I didn’t. I pulled them out and put them on. Glad that I did.
