Organic cotton racerback vest. Simple, comfortable and very versatile! Climate Neutral / Ethically Traded. 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.
