Alpina Sonic HR V - Cat 0-3

Built for speed, precision and fast-moving adventures, the Alpina Sonic HR V delivers high-performance optics in an aggressive frameless design made for athletes who demand unrestricted vision and lightweight comfort. Whether you’re attacking technical MTB descents, logging fast road miles, hiking exposed trails or pushing the pace on a run, these streamlined sports sunglasses are engineered to stay secure, clear and comfortable in constantly changing conditions. 

At the heart of the Sonic HR V is Alpina’s advanced Varioflex lens technology, automatically adapting the lens tint to changing light conditions within seconds. The photochromic lens darkens in bright sunlight and brightens again in lower light, making these sunglasses ideal for mixed woodland trails, changeable mountain weather and long endurance days where light conditions shift rapidly. The extended wraparound lens profile also offers enhanced protection against wind, cold air and trail debris during fast-paced movement.

Designed to remain stable during high-intensity activity, the Sonic HR V features rubberised temple tips and individually adjustable nose pads for a locked-in fit without pressure points. The lightweight rimless construction reduces weight while maximising airflow and peripheral vision, helping you stay focused during technical riding and demanding efforts.

Fogstop coating helps prevent condensation during hard climbs and humid conditions, while the hydrophobic lens treatment repels water, sweat and dirt to maintain clear vision when conditions deteriorate. Mirrored lens coatings also reduce harsh glare and reflected infrared light, providing greater visual comfort in bright environments. Full UV-A, UV-B and UV-C protection keeps your eyes protected throughout long days outdoors.
