A seamless, lightweight soft cotton/lycra compression knit for a snug fit that warms and supports the hand. The unique design helps improve circulation, reduce swelling, and relieve arthritis pain. The open fingertips allow full freedom to feel and grip all day. Wear by themselves or as glove liners for maximum comfort while you are doing your favorite activities. To determine your size: measure the back of your hand across your first set of knuckles: Small: up to 3-1/8", Medium: up to 3-1/2", and Large: up to 4". The lycra allows skin to breath and keeps hands dry. Care: hand wash, air dry.
