ELASTIC SHORTS MADE WITH RECYCLED MATERIALS. Play for the planet in these adidas tennis shorts. Elastic fabric and ergonomic lines provide comfort in all movements. The rear ventilation panels promote breathability. And to top it off, they were made with Primeblue, made with Parley Ocean Plastic. By itself, it's not a smash to do away with plastics, but it's a good turndown service. This product is made with Primeblue, a high performance recycled material made partially from Parley Ocean Plastic.
