Our versatile long sleeved button neck polo can be worn on its own or comfortably under a jacket. 100% Merino wool from the renowned Zegna Baruffa Mill in Italy, we've used a super fine 27 gauge, fully fashioned with a folded knitted placket and dropped back shoulder seam, to create a clean profile. And talking of clean Sulby is also machine washable (woollens cycle with a low spin speed, max 30°C).
