Because our lids are designed to be worn forward or backward, Mike’s ProLids do not fit like a traditional lid. We use an open cell foam in the liner which compresses without adding much pressure to the head. The liner is removable and washable.

Our lids come with 2 liners. One liner is a S/M and the other is L/XL. You can try out each liner and adjust them to find the right fit for you. Our larger shell, the XXL/XXXL comes with one XXL/XXXL liner.

The easiest way to be sure a lid will fit is to measure your head circumference and choose a size based on the sizing chart on our website. You can find that here:

Mike’s ProLids are novelty lids and do not have a D.O.T. certification at this time.

Mike’s ProLids are designed to look like a baseball cap. We did not want the lid to look like a perfect dome so the design may look like there is a slight dent on the side. However, scratches are not part of the design and may occur during shipping. If you receive a lid with scratches please email us at [email protected] and we’ll get it fixed.
