I have been a fan of David Archy underwear for years and wanted to try their thermal bottoms. I��m 6��4�� tall and finding long underwear that fits well has been a problem. These not only fit well (they hug your legs without squeezing you but leave room for the man bits), they come to my ankles without riding up. The fabric is soft and stretchy enough to move with you. I would recommend them if you want a mostly cotton long underwear that fit and work great.
