Sleefs are one of my favourite men's tights brands. 
 
These are very stretchy. I have big legs and they cover me fine. 
 
Be warned they aren't thermal and can become sheer at stretch - for me at least seethrough tights with very few other clothes was what I was after anyway.
 
I am 6'0" (183cm) and 215lbs (95kg), with a 34" waits, and it fits me well.
