Fruit of the Loom Men's V-neck

Are these shirts thick enough so they aren't see through like other white tees? I have dark nipples - if you're wondering.

Are these really lightweight, like thinner than a regular tshirt? I am trying to replace some undershirts for my dad. He won't wear the thick type.

Are they v neck

Is the Fruit of Loom logo blue (as in older design/fit)?
