Alpine’s universal earplugs are made of the unique AlpineThermoShape™ material. Body heat makes this thermoplastic material softer, allowing the AlpineThermoShape™ to perfectly take on the shape of the ear. This gives the Alpine earplugs a perfect fit, stay into place and making them extremely comfortable.

This unique thermoplastic material is developed exclusively by Alpine and is hypoallergic. Most earplugs with filters on the market are made of silicone. Silicone earplugs are much harder and contain colorants. Because of this silicone earplugs may cause allergic reactions.

AlpineThermoShape™ material:
is hypoallergic
is silicone free
is latex free
does not contain any colorants
does not cause any allergic reactions
does not contain any plasticizers
