Long sleeved organic cotton top. Great for layering or on its own. 100% Organic Cotton and Climate Neutral. Why Choose Organic Cotton? Organic cotton is considered by many to be the most eco-friendly fabric behind hemp. It has all the same properties as its traditional non-organic variety, but by choosing organic cotton you avoid the negative consequences of pesticide and insecticide use in farming that result in reduced soil fertility, frequent water pollution and damage to the health of cotton-pickers and animals.
