Siraya’s aerodynamic Alpha professional sunglasses feature extended temples covered in a secure rubber mesh that grips the sunglasses securely on your head, even when you’re perspiring under the sun. Alpha also has a top cushion to shield the eyes from forehead sweat, minimizing potential eye irritation from perspiration. Alpha also feature an adjustable rubber nose piece that prevents slippage and irritation.
Siraya’s Alpha professional sports sunglasses are made of TR-90, a Swiss developed thermoplastic material that is extremely durable, flexible and lightweight. This flexibility makes the Alpha frames extremely comfortable, as well as resilient to damage when met with high impact collisions.
All Siraya professional sports sunglasses come with ZEISS lenses made in Italy, but each frame has different lens color and coating options, each with their own unique properties.
