A superior cotton duck woven in Switzerland with American grown extra long staple Supima cotton. At 460gsm/13.5 oz it is woven thick and dense enough to be water resistant (but not water proof) and a F0 DWR helps s well. The best part of the fabric though is how it captures both sides of cotton’s dual nature at once. The dense and thick canvas weave gives it a rugged hardness and the beautiful Supima yarns give it a gentle suppleness at the same time. And that’s just when it’s new, this fabric should break in beautifully and develop tons of character over time.
