by ENT ( Era, Nose and Throat), the U.S. National Association of Otolaryngology Physicians.  

They are earplugs pre-printed in Kraton, a special hypo-allergenic silicone, soft and flexible making them easy and comfortable to wear.

Thanks to the memory of the material from which they are made, which allows the caps to adhere completely to the skin, they fit perfectly to the shape of each individual ear. I Doc's Proplugs are vented caps, comfortable and not at all invasive.

As they do not enter deeply, they leave intact the natural layer of earwax that waterproofs and protects the ear from microorganisms.

They also help maintain the internal temperature of the ear canal, preventing cold water and wind from irritating the duct, thus preventing inflammation.  

Available in 8 sizes: T, XS, M/S, S, M, L, XL, XXL.    

N.B.: These caps are either transparent or red in color and are sold based on stock availability.
