Featuring our G.R.S certified Recycled Chevron Polyester The Project One Impact Features a Enhanced touch on the skin and a smooth overall finish. It’s supreme 4-way stretch allows for a freedom of movement not available in a recyclable materials until now. With 78.6 bottles of recycled plastic in each vest Our P1 Vests sacrifice neither quality nor the earth. Whenever you see the Project One logo on a product it means we have sourced a material, adhesive, or finish that in someway is a more sustainable version of the materials we could have used. This is not a luxury. This is not a gimmick. Day by day, week by week, year by year. We must strive to be better version of ourselves.
