From the man of the family. I got these to use as lightweight longjohns during these cold winter months. They are tight and I do have to work a little at pulling them on, but they’re a lot thinner than the old longjohns and I can wear them under normal clothes. In combination with sweatpants, they keep me a lot warmer and even help stop wind penetration. They are stretchy and breathable, and because they tend to wick moisture away, my skin stays dry.Because they are mostly polyester with a little spandex, it’s best to wash on cool and hang to dry (which doesn’t take long).
