Made from the truly remarkable bamboo plant. Bamboo also has a super soft feel to the touch. This versatile slubby cloth has a distinctly raw 1930's look. At 230 grammes (8oz) these polos have a nice weighty heft about them and with taped seams. Nipped slightly at the waist for a slimming effect and with a rounded sporty tail they can be worn tucked in or out.
