Made of recycled plastic. These pants use slightly less water bottles than the grey tights and the Original Bella pant (which each use approximately 25 plastic bottles) as the material is lighter, softer and more breathable. The pattern on the back side is also slightly different than the original Bella Tights. Comfortable high waist, pockets, sweat wicking material. Made to move with you and love the shape of you. Our customers love the way these pants feel. The logo on the back is black made to blend and shine only in certain lighting. The perfect pant for yoga, running errands, gym & life!
