With a bow to more classic lens designs while going for the wide field of vision offered in its spherical lenses, the Electric EGB2 Goggles with Bonus Lens offers the widest peripheral vision of any cylindrical goggle. So when you're in mid-air rotation trying to keep a good eye on your landing, or weaving through tight trees, you can rest assured that the wide field of vision these goggles provide will help you see your way through. Beyond the oversized lens and frame design, the goggles have a number of other features that keep you consistently seeing clearly during long days on the mountain or at the snow park. The dual lens design, anti-fog lens treatment, and lens and frame ventilation keep the goggles from fogging up, while an anti reflection coating on the lens and Eye Black light-absorbent paint on the inside of the frame reduce glare. When you're at higher elevations, pressure buildup between the lenses can cause optical distortion, so a pressure valve is placed on the lens to prevent this from happening. The articulating strap enables helmet compatibility and keeps the goggles securely on so you don't loose your eye protection mid-air or mid-run, and the anti-scratch coating on the lens keeps these goggles lasting through many winters. Electric throws in a bonus lens and microfiber bag with these goggles so you have a second lens option and a good way to carry and protect them (or hide them from your mischievous younger brother).
