F74 Turbans are the lightest material we have. F74 was made in white, years ago by a specific mill. That mill has since closed and there is another mill that is producing F74 with the same thread count and weight.
The Really Really Light Pink F74 Turbans are available in 2-4 meters. This color is as close to white one can get, it is got one drop of color in it to give it a slight pink color.
