Alot of people seem to like them, although I don't use them when smoking and outdoor cooking.
What I prefer and works best for me are Chemical Gloves. I have several pair of both Black and Blue ones. Try to find ones that are of good quality, fit well and are flexible. In high temp conditions, you can slip on a pair of cheap white cotton garden gloves before putting them on. In most Smoking conditions, this is not necessary. 2 pair rest on my work table by my Smokers and a couple stay in the kitchen working area.
They are pefect for hand-pulling pork (My preferred method). Afterwards, clean them up by wearing them, squirt a little Dawn in the palms and go through the motions of washing your hands. Set 'em aside to dry.
