100% GOTS Certified organic cotton Interlock is ideal for dresses, T-shirts, and even pants because it is heavy enough. Interlock fabric has a lot more stretch than jersey knit; additionally, it looks the same on both sides of the material because the yarn is drawn through the center, between the two sides. Manifutura 100% organic cotton interlock never-out-of-stock (NOoS) lines are available in gorgeous plain colors such as ivory, navy, grey melange, bright white, black, etc, and hence the name, they can always be found in our stock.
