+ ECO-DESIGN
At Bollé, we don't claim we are going to save the planet, but we do strive to reduce our impact. From AW22-23 onwards, all our new winter sports products are eco-designed with more than 20% recycled or bio-based materials (percentage in weight). For instance, we use recycled polystyrene for the inner shell and recycled polycarbonate for the outer shell of our helmets. As for them, our goggles' frame and adjusters are made with renewable castor oil.
