Not bad. The comfort of latex underwear comes from natural latex. Natural latex has thousands of tiny mesh air holes, which can discharge the residual heat and moisture discharged by human body, promote natural ventilation, provide the best natural air conditioning system, and keep the air inside underwear fresh and healthy. Oak protein contained in latex can inhibit the latent of germs and allergens, which meets the requirements of environmental protection and can inhibit the breeding of germs and mites.
