Got these for my husband who in paralyzed and sitting all the time. He is about 6 feet tall, long legs. Would normally wear 2xl. theses fit well.  lots of length in the leg and in the seat, no drifting down...down...down throughout the day. He likes them but prefers all cotton. I read the tag and reminded him they are all cotton, and this is why i try to shop for him.  :)  LOL  we will buy again, wish for more color choices. :)
