The One Way from Maui Jim is a rectangular-style sunglass model designed for both style and performance. According to Maui Jim’s South-Africa site, it’s described as: “Constructed with carbon fibre, this style presents a hypoallergenic, lightweight and durable framework … perfect for leisure and active lifestyles.” 
So the emphasis is on high-quality materials (carbon fiber), good build, and that Maui Jim lens technology for clarity and glare reduction.
