This pair of gloves improves blood circulation to help relieve arthritic pain while you sleep. Encasing the fingertips—a design unique to Hammacher Schlemmer—the gloves exert a gentle compression and are lined with a patented material that facilitates blood flow to reduce swelling, improve the mobility of joints and ligaments, and help relieve arthritic pain. A study performed by Victoria University in Melbourne, Australia showed the gloves increase blood circulation in hands by 20.7%, helping relieve stiffness and pain. The gloves wick away moisture and allow hands to breathe to ensure comfort during the night. The gloves are made from a flexible, comfortable material that allows fingers and hands to move normally. For proper sizing, measure the circumference of your hand around the knuckles. Specify unisex sizes S (7"-7 3/4"), M (8"-9"), L (9 1/4"-10 1/2"), XL (10 3/4"-11 1/2").
