Nitrile Gloves are a form of protecting hands. The glove material is a nitrile compound, which is a chemical and puncture-resistant material. Nitrile is basically a synthetic reprocessed version of latex. 

Nitrile is a synthetic copolymer, formed through acrylonitrile and butadiene combining.  Nitrile gloves begin their life as rubber from rubber trees. They are then converted into latex rubber.  After they are made into latex rubber they are again reprocessed until they turn into the nitrile compound material. 

The extra step of processing in the glove creation process was originally why when nitrile gloves first hit the market they were so expensive compared to latex. However technological advancements have lead to more cost-effective practices in the making of nitrile gloves. Nitrile gloves are now just as affordable as latex gloves. Nitrile gloves have lower allergy rates.
