The Landyachtz Slide Glove is made with durable leather for maximum strength and durability, double thick where you need it: in the thumb, on the fingertips, and on the knuckles. They feature an elastic cuff with a Velcro strap, so the cuff wont hang down and get caught while sliding. The pucks are made of UHMW and are secured to the gloves with super tough Velcro, so you can replace your puck when it finally wears down.
