Once you shenan, you'll shenanigan in our festive St. Pat's day tees! Not only are they green, they are green because they are a sustainable tee that uses an equivalent of up to 6 recycled plastic water bottles. They are super soft 4.2-ounce, 50% recycled polyester, 25% organic ring spun cotton, 25% modal. They run a little small so if you like a more relaxed fit, we recommend you size up.
