Product Details

The Charles frame is handcrafted by three family-owned factories in Northern Italy. The Charles is made with TR90 polymer plastic – produced with Swiss technology as a thermoplastic material that is incredibly durable, flexible and adjustable. The result is a frame that’s hypoallergenic, holds its shape after contouring to your face, and is resistant to damage because of its ability to bend under pressure. Most importantly for runners, The Charles is extraordinarily lightweight, with a barely-there feel that stays put at high speeds.
