We Are Plastic Neutral

PROTECTING OUR OCEANS FROM PLASTIC WASTE

Making high-quality shades is the core of what we do, but inevitably that means we contribute to excess plastic byproduct. The idea of being a net drain on the environment doesn’t sit well with us, so we partnered with CleanHub to recover and remove plastic waste before it can reach our oceans!
