- A fine Saturday afternoon in Melbourne, circa 1995, 3 bike couriers decided that the Simple & Tenacious Messenger bags they were making for themselves should be available for everyone. That moment birthed Crumpler, rooted in Simplicity, bike practicality, sturdy construction, beers and fun for all.- We sat down with the Crumpler team in their studio space in Melbourne’s CBD to begin crafting the foundation and ideas behind this collaboration.- The result is a uniquely versatile pair of sunglasses, handcrafted from Radios’ plant-based acetate. Available in four colours, this unisex design features Radios’ new Sound Reflection temple core, our iconic checks on the front, and a silver-plated Crumpler x Radio badge on the inside. The lenses are made from high-quality polarized nylon, complemented by sturdy 5-barrel hinges.- Sunglasses designed to be unisex. - Frame: Handcrafted Cellulose acetate – Biodegradable & Plant-based.- Lens: Polarised High quality Nylon lenses with 100% UVA/UVB protection. - Hardware: Durable & Sturdy 5 Barrel hinges in Gold colour.
