Grey cap made with 100% Moon's of England finest wool. Moon's are, of course, the manufacturers of fabrics to Her Majesty's armed forces, so this should last, and last. The cap is lined with Italian silk. Beautiful product, expertly hand crafted in England. Simon Carter at his best. These caps do come up a little large so you might want to go a size down - but we are happy to exchange at no cost to you for another size if it doesn't fit perfectly.
