A super light polo made from 18.5 micron Merino, this Cirrus is summer ready thanks to moisture managing wool blended with a bit of nylon for a lighter touch. Its straight bottom hem pairs well with shorts for a do-everything, regular fit shirt that rolls from boardroom to board shorts. Our lightest weight Merino polo. Regular Fit. No button placket. Straight hem with side vents. A nylon core is wrapped with wool to create a hardy fiber without bulk or weight. Weightless Wool is designed to be softer, more durable and lighter than synthetic workout fabrics. A perfect fabric when used alone for warmer days of aerobic work or layered to add warmth in colder activity. 145g/m2. 87% Merino, 13% Nylon.
