Smaller lens vents prevent fogging when you're sweating. These sunglasses feature a vented half - frame, fully adjustable ear and nose pieces, and come with a case. The Grilamid TR - 90 frame and hydrophilic rubber ensure comfort. They also provide UV protection and are optically decentered for a great view. Slip them on and enjoy a distraction - free workout.

Using these Tifosi Rivet sunglasses is easy. Just put them on like you would any other pair of sunglasses. They're perfect for cycling, playing sports, or any outdoor activity. When it comes to cleaning, use a soft, dry cloth to wipe the lenses and frame. Avoid using harsh chemicals as they can damage the lenses and the frame. Also, make sure to store them in the included case when not in use to prevent scratches. If you're adjusting the ear and nose pieces, do it gently to avoid breaking them. These sunglasses are designed to last, but proper care will keep them in top condition for a long time.
