• Unique Flex Stem™ and triple flange design allow for a more customized fit, which increases sealing ability and improves wearer comfort
• Pre-molded silicone will not deteriorate like similar earplugs made of plastic
• Helps prevent swimmer's ear and surfer's ear
• Washable and reusable for extended wear

Unlike industrial flanged earplugs originally designed to seal out noise (then sold for water protection as a secondary market), Mack's^® AquaBlock^® were designed and tested specifically to seal out water from the start.

Shatterproof carrying case included

MACK'S AQUABLOCK EARPLUGS TESTIMONIALS:

• I surf 150-180 days a year and Mack's AquaBlock Earplugs work great. They are small enough to get in there and won't come out even during a good fall or after taking several waves on the head. For the price, Mack's AquaBlock are the best on the market for water protection.

• Mack's AquaBlock Earplugs work very well. I live in Kenya (I'm back for a few months) and I go to the university there.  I'm a member of the swim team and I don't think they maintain the same sanitization/chlorination levels in the pools there. Whatever the reason, my ears would ache as if I'm scuba diving 30 feet under water. Major pain.  I had to stop swimming for a while until I started using these. Mack's AquaBlock Earplugs WORK!

• I tried the Mack's Aquablock Earplugs, and they were perfect. They were a breeze, and when kept well, reusable. I love them for working out in the pool! I highly recomend them.  P.S. - My ear canal is on the smaller size and they still fit great.
