The Marathon goggles are distinguished by the reduced size of their peripheral, water-repellent, Category 3 sunglass lens, their anti-fog ventilation system known as Airflow® Technology and their nosepiece adaptable to the characteristics offered by each nose. The absence of a spoiler above and below, along with the rest of the established design, results in a very light mask with a net weight of just 24 grams. Recommended for runners of all kinds.
