Designed for children, age Birth - 8 years. Can be worn on bare knees, or over tights, pants and leggings. KneeBees knee pads can be used either indoors or outdoors and made out of soft, stretchy and breathable cotton blend, specifically formulated to offer outmost knee comfort. KneeBees are a unique, patented, double-layered design, which works as follows: upon impact, the outside layer of KneeBees absorbs the abrasion. The inside layer of KneeBees, which is close to the skin, stays in place, thus protecting the knee from scrapes, scratches, scuffs. Machine washable in warm water. May be tumble dried. Do not bleach. Imported. PLEASE, NOTE: KneeBees are very stretchy and therefore, highly adoptable to any knee size. If they feel too tight on the knees, feel free to stretch them with your hands to desired width. Stretched too much? No worries! Just wash KneeBees and they will go back to their original size, so you can try again.
