My Little Cozmo Earth Day Everyday Tee. For us, every day is Earth Day. If you feel the same, this organic cotton baby T-shirt, made in 100% GOTS-certified organic cotton, is the piece you have been waiting for. Featuring our 'earth day everyday' printed graphic design, this tee has a button opening at the shoulder and a ribbed collar. Plus, it has a slub texture which gives it a softer feel and extra breathability.
