INDERAMen's Long Drawers - Heavyweight Thermals Cotton Heavyweight Thermal Shirt

I don't see a size chart. Would these fit a 6" 1" tall man? And what about waist size? What size would a 34" waist be (medium?)

The product description indicates it's a "men's tall" but in the select size drop down box, it only indicates "regular sizes." are they all "tall's?"

Are these fleece lined?

Is there any difference between heavyweight & regular ones?
