Designed in universal size for adults. The eyepieces have mirror adjustment so that they can be used even in outdoor swimming without any problems. Mirror-colored goggles provide protection against sunlight and glare, but it's also a design issue. Antifog is an antifog layer inside the eyepieces. This layer significantly reduces glare. Do not wipe your goggles with any handkerchiefs or touch them, damage the anti-fog layer, and the goggles will become foggy. UV-filter absorbs dangerous UVA and UVB radiation, which can damage your vision. The goggles with UV-filter are suitable for outside and inside swimming. The swimming goggles hold on the head only with the help of one strap. Its simple advantage is the fast deployment and easy handling. This type of simple strap is most commonly used in children's swimming goggles. These goggles have a sliding nose bridge. This type of nose bridge is fixed to the goggles and can be moved to several positions. This will ensure the proper distance between the eyepieces that best suits. It is designed as unisex.
