A lightweight google with a super wide field of view that's perfect for backcountry conditions. These feature Julbo's Spectron 3 polycarbonate lens with a red tint that's well suited to medium to full sun conditions. The frameless design is optimal for small to medium sized heads. A three part system also makes these totally fog proof: ventilation around the frame, a double lens construction, and an anti-fog coating on the inside. The integrated strap has a silicon surface on the inside to prevent slippage on your helmet. Perfect for long days on the mountain!
