Every pair of Coastline Sunglasses includes a 100% recycled PET sunglasses pouch, and is carefully packed in 100% recyclable, plastic-free packaging. Try on at home with free UK returns via Royal Mail, and reliable worldwide shipping wherever you’re based.
Our frames are built with our 100% recycled Traceable Marine Plastic (polypropylene) that we have recovered and recycled in the UK. For every frame you can trace the exact locations of where the plastic for your batch was recovered from.
Polypropylene is a lightweight, durable polymer, commonly used in fishing gear such as ropes, bait bags and mooring lines.
In the marine environment it poses a major entanglement threat to marine life, but its recovered and recycled form, it's a strong plastic suited to a very broad range of uses, and helps to give our frames a flexibility that, when heated, allows you to make adjustments to your frames at home.
