Ergo Earplug

Arena just made using earplugs while swimming even easier.

 The colour-coded Ergo earplugs simplify identifying which side you use each plug on.

 Made of ultra-soft silicone and arena's Liquid Core Technology, Ergo is the most comfortable earplug yet.

The hollow stems make them quick to grasp and improve hearing underwater. Seal out the water, seal in your focus.
