We've used 100% Egyptian cotton, crafted into a quality two-fold 100s construction to create a fabric that's strong, resilient and, delightfully smooth to the touch. Thanks to the split-back yoke, you have total freedom of movement, so slipping into this piece feels like power dressing. It's Tyrwhitt down to the details, including signature detailing of side gussets and back neck piping, heat sealed shanked buttons for a more secure and long-lasting button attachment and the fabric's subtle sheen designed to give a luxurious feel.
