• Read instructions and review warning
• Do not peel apart the layers of the Dome
• No adhesive required, drops right in and tucks behind the sweatband
• If trimming required, do not trim the front tab (A)


The Dome can be customized to the exact shape of your fabric cap. It is designed for a large to extra-large fabric cap, but can be trimmed to fit small and youth sizes

Align the large rounded tab (A) with the front of the cap. Make sure the waffle pattern is facing your head

Place the Dome inside the cap and press it into place. Tuck the front and then the side tabs under the cap’s sweatband. Trim back tab as needed to slide under sweatband

If the back tab needs trimming, mark a line where the overlapping tab should align with the base of the sweatband. Using normal sharp scissors, cut the excess back tab along the line. Do not trim the front “roundish” tab or sides

Place the Dome back into the cap and tuck all the tabs under the cap’s sweatband

Remove from cap and hand wash with soap and lukewarm water. Do not submerge the Dome into water. Air dry.

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.
