Sleeves for Trees Collection on Organic Cotton Hoodie Geometric Bison

 Bison are Ice Age survivors. Clearing away snow and brush with their massive heads, they weigh up to 2,000 pounds and can run up to 40 miles per hour. Once numbering 30-60 million in North America, their numbers were decimated in just a few decades as expansion pressed westward. No other species on Earth has declined so quickly. Several Native American tribes are working with WWF to grow bison numbers once again across vast grasslands under their management. The plains bison is the largest land mammal in North America with some adult bulls weighing in excess of 2,000 lbs. Tens of millions of these iconic animals once roamed across much of North America. Today, the largest remaining wild herd of approximately 4,500 individuals can be found in Yellowstone National Park. Donations will be made to the Wildlife Conservation Society.
