Ethical meets exceptional for your everyday tee. Purposeful and durable, this tee is made from in-conversion organic cotton to support our farmers and environment. In a growing process that takes about 3 years, we’re collaborating with farms to transition to certified organic fields. The Principle Base tee is an slim-fitting, quintessential base layer that is finished with our signature railroad stitching. It can be worn as a base layer or undershirt, but also stands on its own. Quality guaranteed, sustainability added for good measure.
