p>From downhill mountain races to trail runs with plenty of obstacles, the Julbo Aerospeed Spectron 3+ Sunglasses are there for the ride, no matter how bumpy. The ultra lightweight frame won't shave any seconds off your timed course, and a dampening temple system helps absorb shock as you're bouncing around on rocks and roots. As a larger version of Julbo's popular Aerolite, the Aerospeed offers panoramic views of the trail ahead, so nothing will take you by surprise, and the Spectron 3+ lenses have a flash finish that improves filtration of visible light by applying a mirror effect to help you see clearly in various conditions.
