These are low rise. Extraordinarily comfy. Don't wrinkle. Look like pants, but also work as sweats. Have a zipper pocket. They are warm in the cold, but the fabric has a sort of "crinkle" texture, so they breathe really well.
Since they're wool they avoid the stinky issue from travel. They can be washed in the machine.
I bought a pair on sale that were the wrong size. Had to send them back. Even though the fit was wrong, they were soooooo comfortable I hated to send them back. I might have to buy another pair now that they're in stock again...
