SWANS ASCENDER SR-81M | PREMIUM ANTI-FOG | OPEN WATER

The Ascender is built for swimmers who demand more from their vision — in the pool and beyond. Its signature curved lens design delivers a noticeably wider lateral field of view, giving you better spatial awareness whether you’re racing a wall or sighting a buoy in open water.

The curved lens reduces water drag, while the 3D cushion is engineered to stay locked in position through dives and turns; no shifting, no mid-race adjustments. Polycarbonate lenses provide 99.9% UV cut, and every Ascender comes fitted with Swans’ Premium Anti-Fog (PAF) coating, optimised specifically for swimming environments for consistently clear vision from the first lap to the last.

World Aquatics (FINA) approved for competition use, the Ascender transitions just as naturally from training to race day. Available in mirror, normal, polarized, and photochromic lens variants — the photochromic version automatically adjusts lens darkness based on UV exposure, becoming darker in bright sunlight and lighter in overcast or low-UV conditions, making it ideal for outdoor and triathlon swimmers.
