Warmth and lengthened cuffs to help seal out water make the Synergy Neoprene Swim Glove a favorite with triathletes and elite swimmers for training in varied weather conditions. To find your glove size, measure (in inches) around your hand with a tape measure across your palm. You should use your dominant hand, the right if you are right-handed, and the left if you are left-handed. Measure around the hand at the fullest part (exclude thumb).
