I'm 5 8" i was worried that the pants would not be long enough that's why i purchased Tall M. Now they are too long. I knew there was a lining but didn't expect it to go all the way down. Makes them definitely warmer than needs to for the hot weather. ( in my opinion you can easily remove the lining if you want to.I'm thinking about it)But definitely not see through! Now I would like to exchange them to a regular size. But everything else about them is so good: the fabric, the style! Very classy!
