The Official Earplugs of USA Swimming. Keep the Water Out.

Mack’s AquaBlock Earplugs are the trusted choice of elite swimmers and the Official Earplugs of USA Swimming — engineered with SuperSeal Ultra Soft Silicone and a triple-flange design to create a watertight seal that keeps water completely out of your ears. Whether you’re swimming laps, surfing, snorkelling, showering, or kayaking, AquaBlock delivers doctor-recommended protection against swimmer’s ear and surfer’s ear — every time you get wet.

SuperSeal Ultra Soft Silicone – Extreme Comfort

Pre-moulded and flanged from SuperSeal Ultra Soft Silicone, AquaBlock earplugs are designed for extended wear without discomfort. The silicone is exceptionally soft and flexible — gentle against the ear canal, non-irritating, and latex-free for safe use by those with sensitivities. Comfortable enough to wear through an entire swim session, a surf, or a long shower without needing to readjust.

Triple Flange & Flex Stem – Customized Waterproof Seal

The unique Flex Stem and triple-flange design allows for a more customized fit that adapts to the individual shape of your ear canal — increasing sealing ability, effectiveness, and comfort simultaneously. The easy-to-grip stem makes insertion and removal simple, even with wet hands. A secure fit means a secure seal — no water gets through.

Doctor Recommended – Prevents Swimmer’s Ear & Surfer’s Ear

Mack’s AquaBlock is doctor recommended for preventing swimmer’s ear infections (otitis externa) and surfer’s ear (exostosis) — two of the most common and painful conditions caused by repeated water exposure in the ear canal. Trusted by medical professionals and elite athletes alike for reliable, consistent water protection.

Durable, Washable & Reusable

Made from high-quality, long-lasting silicone that will not deteriorate or degrade like plastic earplugs over time. Fully washable and reusable — rinse, dry, and store for the next use. Each set of 3 pairs gives you multiple backups for home, gym bag, and travel kit.

Durable Storage Cases Included

Each pair comes with its own durable carrying case for on-the-go convenience — keeping your earplugs clean, protected from dust, and ready to use whenever you need them. Compact enough to slip into a swim bag, beach bag, or travel kit without taking up space.

Versatile Water Protection

Purpose-built for swimming, surfing, snorkelling, showering, kayaking, rafting, and bathing — any activity where water near the ears is a concern. Hit the pool, the waves, or the shower with complete confidence that your ears are protected.

Material

Constructed from SuperSeal Ultra Soft Silicone — high-quality, medical-grade flexible silicone that is latex-free, non-toxic, and hypoallergenic. The silicone is durable enough to withstand repeated use and washing without losing its shape, softness, or sealing effectiveness. The carrying case is made from rigid durable plastic with a secure snap closure to protect the earplugs between uses.

The earplug elite swimmers trust. The protection doctors recommend. Keep the water out — every time.
