The new Magic YoYo YoStyle Premium Glove is a high-end lycra glove that should fit most YoYo players. It has a very smooth surface so that you will get minimal friction on the string while you play.
These gloves are a step up from the cheaper Magic YoYo gloves - with quality stitching and printed branding on both sides of the glove. These gloves come in three colours: black, maroon and blue.
These gloves have a one-size-fits-most size. Please see the below image to see some approximate dimensions of the glove, to give you an idea of whether or not it will fit you. Remember, it is a stretchy material, so it does stretch somewhat. It is probably not suitable for someone with huge hands though!
