There is a company called Direct Safety that sells just about every kind of protective gloves you can imagine. They have about a dozen different kinds of Nitrile gloves as well as latex, vinyl, and PVC. All their gloves come in multiple sizes.

Direct Safety also has a dazzeling array of safety gear... eye and ear protection, respirators, boots, tyvec suits, and lots more. Anyone interested in shop safety ought to have a look at their catalog.

As far as I know, they don't have a web site but you can call them at 800-528-7405
