Each cap you see is uniquely made by an American artist.
Be sure to check the photos for the hole size that you like.
A smaller hole can result with a tighter airflow (it will feel harder to get air).
A wider hole can feel like too much air is coming through.
Try to compare the hole sizes on any cap you own and like to the ones below in the photos. If you don't like a cap you purchase from us, contact us right away. We will help out however we can.
