This navy promotional cap combines classic styling with functional design elements. Constructed from a durable 60% cotton, 40% polyester blend, it features an embroidered Western Hydrodynamic Research logo on the front crown. The standout feature is the WHR shock cord bungee closure system, built with a nylon-cased, multi-stranded rubber core secured by brass grommets to prevent pull-outs. Designed and tested in California by the WHR Institute, this cap represents a patented approach to headwear functionality.
