The cap is made with Coolmax fabric. Coolmax wicks away moisture to keep you dry and comfortable.

Squeeze together and it stays.

Fold over the adjustor strip.

You can also adjust the fit of the Underhair. A self-adhesive strip is sewn at the back. Just fold it over as much or as little as needed then squeeze it together. Change the fit anytime by pulling it apart and re-adjusting.

A thin polyeurethane elastic is on the inside edge. It has a grippy feel to help keep the Underhair secure without having to be tight.
