Our Outback Offgrid Explorer Cotton Cap holds it shape great . It is a structured 6-panel cap with a pre-curved peak. The Heavy brushed Cotton fabric our Explorer Cap is made from is keeps it looking great. The back fastener on our Outback Offgrid Explorer Cotton Cap is the hook and Loop style. The vent eyelets in the top are stitched. We choose this option so there is no metal on this cap anywhere. This makes it the perfect choice for saltwater environments and can be washed without having to worry about corrosion.
