The Hebo Gravity II glasses are a great option for off-road enthusiasts. They weigh only 160 grams, making them an ideal option for longer sessions. They also have an elastic strap with silicone that prevents unwanted movements in difficult sections. The lenses are removable and interchangeable. They have anti-fog and anti-scratch treatments, and offer UV protection. To avoid moisture accumulation inside the glasses, they have a directional air flow that facilitates proper ventilation. The package includes a bag and cleaning cloth.
