No but I have stood in a fire with my Flying Boots on, and picked cooked food out of the centre of a fire with my issue Gloves!
We wore our flying kit whilst on Combat Survival & Rescue training, what got damaged was replaced, but it was good to test the kit properly.
I was amazed at how protective the gloves were, I could reach into the fire to pull out and check my Poached Trout hardly feeling the heat (I caught 3 Trout on the first night!
)
