Give back to the environment with the 48 Lbs. Sustainable and Ethical Clothing. Offering a simplistic approach to style, these t-shirts and sweatshirts actually help improve the environment. With each purchase, a tree is planted. Each tree then absorbs 48 lbs. of CO2 per year, hence the brand’s name. This cycle keeps the brand both sustainable and ethical in its production of clothing. In addition, the 48 Lbs. shirts use GOTS certified 100% organic cotton yarn. Sustainably sourced, this material helps to give the 48 Lbs. Clothing its premium feel. The shirts are simple yet refined with no loud logos or scratchy labels. Instead, they feature perfectly sized armholes, classic sleeves, and a neckline that won’t stretch out. Plus, the fabric is shrink tested so you know it’ll last and last. The 48 Lbs. Shirt is one that you’ll be proud to wear.
