With the Quickshift MTB Spectron 0, Julbo is revolutionizing the enduro glasses world, as it is the first enduro glasses with SwitchAir system on the market. It consists of two removable parts that affect the ventilation and ergonomics of the glasses. You can remove these parts in no time at all, especially on strenuous climbs, to get fully ventilated glasses with a reduced face contact surface. If you then go downhill again at breakneck speed, you can reinsert the parts for maximum wind protection in just a few seconds. The sports goggles are also equipped with a frameless double lens, giving you an extra-wide field of vision. They fit perfectly under any type of helmet, making them the benchmark for ambitious mountain bikers. With the Quickshift MTB Spectron 0, you can tackle your terrain even faster and harder, both uphill and downhill ... whatever the weather.
