  • Amazing company and product!

    Posted by Peter D. on Jun 1st 2023

    The team at Unequal was amazing for us from start to finish. They really took the time to get it right for our son, beyond our expectations. It felt very personal and we appreciated all of their help, super happy with the products we received from them.

  • Pitcher Worn for Years

    Posted by Bryan on May 31st 2023

    Years ago, I did my research and found that Unequal was really the only company that offered a heart-guard that had clinical trials and was shown to have some effectiveness against Commotio Cordis. I purchased a shirt for my son who was a pitcher through high school and wore it every game. He has since continued on as a pitcher in college and still wears the shirt. There have been no complaints from him about comfort during this time. I know that there is nothing that is 100% effective, but as a parent it does give me a little piece of mind that he has some level of protection.

DISCLAIMER: Unequal reduces risk of head injury, compared to no head protection. Leading medical doctors, PhD’s and scientists have concluded that a reduction in acceleration correlates with a reduction in concussion risk. Any player in any activity, game, or sport, can sustain a head injury even with head protection, and that no helmet, pad or Unequal product can prevent concussions or eliminate the risk of these injuries.
