The Oakley SI Tech Cap delivers a modern, high-performance tactical silhouette designed to withstand harsh outdoor elements and intense physical training. It is constructed entirely from 100% premium polyester engineered with advanced hydrophobic properties to repel water and dry at accelerated speeds. The structured front features a classic hook-and-loop morale patch panel decorated with an engineered, low-profile tonal Oakley ellipse logo for clean tactical customizability. To counter overheating and regulate temperature, the interior layout incorporates a high-performance O Hydrolix mesh sweatband that actively channels perspiration away from the skin. The deep "Fathom" navy colorway offers a highly adaptable, professional look suited perfectly for active operators, maritime duties, or premium off-duty wear.
