Mil-TecMen's Us M64 Vietnam Jungle Jacket

I have an original size Large Long 3rd pattern jacket, would a size Large reproduction jacket be the same chest size?

How easy is it to remove the 'Ryan' name tag, and does it still look good

can you remuve the name tag and the US army tag?

The original jackets were made in ripstop polin: is this replica also manufactured from the same material?
