Nitrile gloves are the perfect compromise between latex & vinyl. Nitrile is made from an allergy-safe compound that feels a lot like latex, but it's much stronger & more comfortable to wear. Glove components comply with the provisions of the Federal Food, Drug & Cosmetic Act that allow repeated use in direct contact with food. Nitrile is perfect for demanding applications, especially cleaning, dishwashing & auto work. They are 100 percent allergen-free because they are 100 percent latex-free & 100 percent silicone-free. Powder-free construction means the gloves go through an extra process of chlorinating the gloves, making it easier to take the gloves on or off. Size medium gloves measure approximately 9-1/2" long & offer a 4.1 mil finger thickness, 3.7 mil palm thickness & 2.9 mil cuff thickness.
