Thumbs up if you're ready for a good day ahead. This adidas tee is all about an optimistic outlook — like the one sported by the animated Trefoil on the front and back. Why so cheery? Probably because it's so comfortable, sitting on pure cotton single jersey for all-day softness. We partner with Better Cotton to improve cotton farming globally. Better Cotton makes global cotton production better for the people who produce it, better for the environment it grows in, and better for the sector's future. Better Cotton is sourced via a chain of custody model called mass balance. This means that Better Cotton is not physically traceable to end products, however, Better Cotton Farmers benefit from the demand for Better Cotton in equivalent volumes to those we 'source.'
