Review on Optimized Flex Weight Thermal Pant for Men by Duofold by Michael Schwegman

I have 4 pairs of old medium weight polypropylene Duofold Long Pants that I love, they are no longer sold and are long gone. I'm looking for a replacement hoping they make it but they don't. As one reviewer said, the waistband is thin, it looks like a regular 1 1/4" wide belt, but it is just a sewn on piece, this belt has a 1/2" wide elastic sewn into it. I don't like it, but in use it doesn't matter. They work great on my cold walks, but they tie into my pants so it doesn't work on my hikes. I think they will adjust to the bottom of the pile while other pairs are in the wash.
