Mack’s ThermaFit Soft Foam Earplugs, 40 Pair - Comfortable Ear Plugs for Sleeping, Snoring, Work, Travel & Loud Events | Made in USA

Product description Mack's ThermaFit Soft Foam Ear Plugs feel firm out of the package, but therein lies the secret to why many consider these the best earplugs ever.

The rigidity of these earplugs make insertion into the ear canal easier than with some competitor's softer foams that can bend and crumple during insertion.

After insertion, the PVC foam reacts with your body heat to slowly expand and fill the unique contours of your ear canal, creating a super comfortable, noise reducing seal.

The cylinder plug design is slightly shorter in length than traditional bullet-shaped foam earplugs, providing a low profile, discreet look.

Mack's ThermaFit Earplugs carry a noise reduction rating (NRR) of 29 decibels to help protect hearing or get a good night's sleep.
