Featuring our G.R.S certified Recycled Chevron Polyester, the Project One Impact Vests features an Enhanced touch on the skin and a smooth overall finish. It's supreme 4-way stretch allows for a freedom of movement which was not available in a recyclable material - 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 some way is a more sustainable version of the materials we could have used.
