Our Neoprene is latex free. If your patient experiences a rash or redness while wearing one of our Neoprene products, it is most likely a heat rash. Redness can also occur if the product does not fit properly and is rubbing against the skin. In these cases, the patient should discontinue use of the product and consult with their doctor. Patients are encouraged to take the fit of the product and their skin sensitivities into consideration before purchasing Neoprene products, as we only warranty our products against defects.
