The Tora™ CCS is an innovation from 3M™. Featuring the Cord Control System which has been designed to keep corded earplugs attached, untangled and ready for use. The cord can also double as a lanyard to carry your specs around your neck when not in use. One of those ideas that you can't believe hasn't been thought of before! Will work with just about any corded earplugs (supplied separately). As you would expect from 3M the lenses are anti-scratch and anti-fog. Approved to EN 166 1F.
