A new series of organic tees has been garnering lots of attention, so consider adding these graphically bold, eco-friendly fashion statements to your holiday gift list.

Know Tees feature a variety of eco-centric and self-affirmation messages—from Know Earth and Know Love to Know Peace (pictured) and Know Courage.

Available in both short and long sleeves, the scooped-neck shirts are made from renewable and sustainable bamboo, organic cotton and a small amount of Lycra to maintain proper fit.

Sizes range from XS to XL, and the tees are machine washable.
