GloWear 8205HL-ECO Recycled Hi-Vis Vest is a Type R, Class 2 vest that meets ANSI/ISEA 107-2020 visibility requirements and is made of 100 percent recycled polyester mesh for long-lasting use and wear. 2" reflective tape offers enhanced low-light visibility. Hook-and-loop closure allows easy on and off. Dual sizing provides a looser fit for wear over shirts, sweatshirts or jackets. Vest is ideal for road construction, baggage handling and municipalities. Recycled polyester is made with post-consumer plastic bottles converted from polyester yarn through chipmaking and spinning. The yarn is then knitted and dyed for proper vest cutting and sewing. Each machine-washable shirt is equivalent to approximately 11 plastic water bottles (16.9 oz.). Small/Medium size with a 25-1/2" long center back fits up to 50" diameter torsos.
