In some case you can get disoriented and the day is over before it started. A great solution for keeping that water out of the ears are Macks Pillow Silicone Earplugs. These earplugs can be reused multiple times before having to toss them. Plus the best part is no longer do you have to shove something into your ears and find out it doesn’t fit your ear canals. Macks Pillow simply molds comfortably to your ears. These also can double as just reducing noise with a noise reduction rating (NRR) of 22 decibels for those flights to your triathlon destination.
