I love this product. Very well made, will outlast your sunglasses. It's my favorite of all the various brands I've tried over the years. The thin strap makes it low profile, but very sturdy. It's adjustable to tighten up when needed to keep your sunglasses on your face, but I usually wear it expanded to its maximum length so I can wear my sunglasses around my neck and not have to hold them or put them away when temporarily taking my sunglasses off.
