THIS IS A GLOVE FOR MUSICIANS TO USE WHEN PLAYING UNDER UNIQUE SITUATIONS AND CIRCUMSTANCES. You can play beyond finger tip fatigue, pain and medical issues. It feels so natural giving you an intuitive, enjoyable sense of fluid fingering and shifting. Many players say the play smoother & faster. Great for the ?on/off? & beginning player who needs to give the fingertips some protection to keep playing as the calluses develop. IF YOU ARE PLAYING COLD WEATHER OR BREEZY GIGS: keep your fingers fully covered, functional and comfortable when playing outside or on a stage with cold air piling down on you! Also moisture-wicking to keep cool, comfortable, and dry in the heat. It?s great for those five-nighters with a rehearsal in between! SIZING IS ACCORDING TO APPROXIMATE MIDDLE FINGER HEIGHT FROM ITS BASE TO THE TIP. It is better to lean more toward the smaller size for the proper 2nd skin fit! XL = 3¾ in. (9.52 cm), L = 3? in. (9.21 cm), M = 3? in. (8.57 cm), S = 2? - 3 ? in. (7.3-7.94 cm), XS = under 2? in. (7.3 cm), XXS = 2-1/2 inches or less (6.35 cm) ONE GLOVE FITS EITHER HAND.
