Our mid-weight fabric looks are designed with versatility in mind - wherever you spend the season. Made with Woolmark-certified wool, the Merino material is breathable and naturally temperature-regulating. That makes it comfortable and flexible in any climate. We've included some stylish Tyrwhitt touches for added panache, including AMF stitching, a Bengal-striped sleeve lining and a bottom jet pocket in your suit jacket - ideal for your mobile phone.
