Endurance adventure or race day, the adidas Terrex Agravic Trail Running Pro WIND.RDY Windbreaker offers lightweight, packable shelter for the trail. WIND.RDY resists wind and repels rain to keep you comfortable and on the move in less than perfect weather. A pleated back panel lets you pull it on over your pack while maintaining a natural range of motion. Its lightweight design makes for easy packing. Ventilated openings on the back keep air moving for climate control. Zip up and keep moving.
