Blackstone griddle gloves. These gloves are heat resistant up to 500 degrees, and unlike oven mitts, you get a great amount of maneuverability. The palm pads are made of 100% silicone, giving you more grip than traditional oven mitts, and the gloves themselves are made of a cotton and aramid blend, giving you flexibility. Made with a textured design for easy grip, the Blackstone Griddle Gloves are perfect for picking up hot casserole dishes and other heavy cookware without slipping.
