It is legal!
Gloves may be worn to assist the player in gripping the club, provided they are plain.
A “plain” glove must:
• consist of a fitted covering of the hand with a separate sheath or opening for each digit (fingers and thumb); and
• be made of smooth materials on the full palm and gripping surface of the digits.
A “plain” glove must not incorporate:
• material on the gripping surface or inside of the glove, the primary purpose of which is to provide padding or which has the effect of providing padding. Padding is defined as an area of glove material which is more than 0.025 inches (0.635 mm) thicker than the adjacent areas of the glove without the added material;
Note: Material may be added for wear resistance, moisture absorption or other functional purposes, provided it does not exceed the definition of padding (see above).
• straps to assist in preventing the club from slipping or to attach the hand to the club;
• any means of binding digits together;
• material on the glove that adheres to material on the grip;
• features, other than visual aids, designed to assist the player in placing his hands in a consistent and/or specific position on the grip;
• weight to assist the player in making a stroke;
• any feature that might restrict the movement of a joint; or
• any other feature that might assist the player in making a stroke or in his play.
