Vintage Work Trucker Vest Mayflower XL

Up for sale is a lightly used King Louie Pro Fit Vest featuring a Mayflower patch in size XL. My Dad worked for Mayflower from the mid-1970s through 1997. This is sort of an off-white color, but I wasn't sure how to describe that given the canned Ebay options. Look at the pictures for a feeling of the color. I'd assume this was from later in his career since it was largely unused.
