These small-sized latex gloves are suitable for gardening, maintenance, and various horticultural applications.

Nitrile Gloves are made of synthetic latex. They contain no latex proteins and offer excellent resistance to punctures and tears. Nitrile gloves are three times more puncture resistant than rubber and can be used to offer superior resistance to many types of chemicals. Unlike latex gloves, nitrile gloves have low resistance to friction and are very easy to slide on.
