Line Miner™ was created with the aim to bring you ultimate field of view. The frame design in combination with the cylindrical lens make the goggles sit closer to your face than ever before, and it allows for outstanding vision even downwards and to the sides. Subtle grooves at the temple of the frame provides compatibility with glasses, without compromising the fit. Line Miner™ also has a removable 3-layer foam for extra protection against the wind. XM stands for a smaller fit, for those with a smaller face.
