These sunglasses are DON'T PANIC, highly rated for running and other activities. The round temples are designed to wrap around the head for an excellent hold, making them comfortable to wear and less likely to slip during intense exercise like running. They are recommended for various activities such as running, trekking, fishing, camping, and golf. I own other lenses, and these were a bit too flashy for me, so I'm selling them. I hope you'll find them useful! I've only used them a few times, and they are in good condition for a used item. The lenses are silver mirror, and the frame is matte black. There are no noticeable damages, but please refrain from purchasing if you are concerned or particular, as they are used and stored at home. Only those who understand and agree are welcome to purchase. The product box will be unfolded and included.
