I currently own two of these. I use my in the kitchen. Being a Big Man it is hard to find a oven mitt that fits. In gloves I wear XXL. This fits with NO problem. It is a great overall oven / grill mitt. I have used it on Cast Iron that is 550 degrees. You don't want to hold it long but you have plenty of time to get it out of the oven and onto the stove top. I love mine so much I am now buying them as gifts.
