These silicone oven mitts are heat resistant up to 600º F and proved to be the most durable in Hammacher Schlemmer Institute tests, thereby earning The Best rating. The Best model's flame and steam-resistant silicone exterior and three-layer thermal liner allowed analysts to hold a 450º F casserole dish for 33 seconds, more than twice as long as any other mitts. When the mitts were partially submerged inside boiling water, the interior of The Best Silicone Oven Mitts remained up to 26ºF cooler than lesser models. The flexible silicone allowed analysts to confidently grasp a baking sheet, saucepot, and even a small potato. The Best Silicone Oven Mitts showed no signs of wear after repeated cycles in a dishwasher. The mitts have 4 1/2" cuffs to protect wrists and a built-in magnet and silicone loop for hanging storage.
