The Aquaduct Zip polo is a versatile garment that can be worn either as a lightweight sweater or as an inner layer. The aquaduct fabric is knitted with two layers, 95% Merino wool, 5% nylon, designed to trap warm air between the layers, the inner layer wicking moisture to the outer layer where it evaporates. It is a tight knit, resistant to wind and rain.

This zip polo neck shirt has extra long sleeves with a thumb hole. The sleeves can be rolled down to cover the wrists and the palm of the hand. The back length of a size M(40) is about 29 inches. The back of the sweater is about 2-1/2 inches longer than the front. The weight is approximately 12 oz. Machine washable (gentle cycle, no softener), dry flat. Made in Norway.
