Description
Orca Killa Hydro Swimming Goggles for Everyday Training
The Killa Hydro is Orca’s low-fuss training goggle: small, streamlined and easy to adjust. The hydrodynamic shape sits close to the face to cut drag through the water, so it suits swimmers putting in regular volume, whether that’s technique sets, threshold work or long aerobic swims.
Fit and comfort
Most goggle discomfort comes from a poor fit around the nose and eye sockets. The Killa Hydro tackles this with a kit of three nose bridges in different sizes. Swap them to match your face shape, and you get a seal that holds without having to crank the strap tight. The ergonomic frame spreads pressure evenly around the eye, which makes a noticeable difference by the end of a long session.
Anti-fog and lens options
Orca’s long-lasting anti-fog coating is designed to keep vision clear for longer than standard treatments. Choose the mirror lens for bright conditions and outdoor pools where glare is an issue, or the smoke lens as a versatile tinted option for everyday training.

Which lens should I choose, mirror or smoke?
Mirror is the better pick if you train outdoors or in bright, sunny pools, as it cuts glare. Smoke is a good all-round tinted lens for indoor and outdoor training.
How do I change the nose bridge?
Unclip the fitted nose bridge from the lens frames and clip in one of the alternative sizes. Try each one. The right size gives you a seal without needing a tight strap.
Are the Killa Hydro goggles suitable for open water?
They’re designed primarily as a training goggle. The mirror lens works well in bright outdoor conditions, but if you swim mostly in open water you may prefer a goggle with a wider field of view. Ask us in store and we’ll help you choose.
How do I make the anti-fog coating last?
Rinse the goggles in cold, fresh water after every swim and let them air dry. Avoid wiping or touching the inside of the lenses, as this wears the coating down.
Will these goggles fit a smaller face?
The compact frame and the three nose bridge sizes make the Killa Hydro adaptable to a wide range of face shapes. If you’re unsure, pop into the shop in Dereham and try a pair.
