Adenna's Shadow® Black Nitrile Powder Free Exam Gloves are an alternative for those who are allergic to natural rubber latex. Formulated with 100% synthetic nitrile polymer, these gloves are latex free, powder free and odor free. The unique thermal sensitive polymer absorbs body heat and conforms to the user’s hand. Adenna’s proprietary technology makes these nitrile gloves softer, stretchier and more flexible than other nitrile gloves.
