The Good Tee’s signature long sleeve white t-shirt is an ideal sustainable basic with a flattering slight contour at the waist and longer length. Made entirely of organic cotton – a fiber that naturally biodegrades once disposed of – this product biodegrades in 20 years, unlike synthetics (such as polyester) that take up to 200 years to decompose. Fairtrade & GOTS-Certified Organic cotton - Super-soft, single jersey - Round self-bound neck - Slightly contoured fit, longer length - Reinforced shoulder binding for added durability.
