Waterproof, Stretchy, Durable, Comfortable, Lightweight and PERFECT SIZES! We offer bracelet sizes ranging from 5.75 inches to 8.50 inches. We have the most inclusive sizing you will find for any bracelets. Our Royal Knight stack includes four total bracelets! (Yes, 4!!) Included in the stack are 4 of our signature tila bracelets with colors of matte black, glossy black, dark blue and light grey. SIZES: To find your tila bracelet size, you can simply order the same size as your t-shirt, or use the chart below. We want your bracelet to fit perfect, so please make sure and measure if you know your wrist size wouldn't be the same as your t-shirt. For men, add a size (for instance, if you are a t-shirt size 2X, order the 3X bracelet)
