On're is a specialist company who supply leggings engineered for performance tennis. Their collection is made up of a range of longer and shorter length leggings in different fabrics which all have a patented "pocket" on the back waistband which can hold up to 4 tennis balls. You can play tennis and these balls do not fall out - we know we've tried them and now wear them every time we play. It definitely reduces the amount of time you spend picking up balls!
