Latex is a natural or synthetic material that is stretchy, durable, and water-resistant. It is commonly used in clothing, gloves, and other personal protective equipment, as well as mattresses and pillows. Natural latex is made from the sap of rubber trees, while synthetic latex is made from petroleum-based chemicals. The material is highly elastic and conforms to the wearer's body, making it comfortable to wear. However, some people may have allergies to latex, which can cause skin irritation and other symptoms.
