Comfort for your Child The length of Ukes is specifically made for comfort and convenience. When your kid is not wearing the glasses, the eye wear strap can lay on their chest instead of high up near their throat. When they are wearing sunglasses or reading glasses, the strap hangs comfortably behind their neck. It's so comfortable they may even forget they are there! Adjust to Your Desired Length Everyone has a different preference regarding how the strap fits on their head. We understand this, and we've designed Ukes to be adjustable by sliding the strap bead up or down. We want to make sure Ukes fit as comfortable as possible. Stay Strapped Sunglasses can be expensive. Ukes sunglasses straps fit securely around the ends of your kids' sunglasses, and keep them on their face. It's inexpensive insurance for your child's sunglasses. Stylish Sunglass Straps Ukes provides sunglasses straps that fit your child's unique personality. Ukes' vibrant colors and designs add instant style.
