Men's Hachi Hood Open Ear
During Japan's pre-industrial era, there was an on-point warrior class known as the samurai. As we all know, these gents came to play, carried swords and wore helmets. The hardest part of their headwear was called the Hachi. Well, your Geoprene Hachi Squid Lid might not stop a Hattori Hanzi blade. But it will block a coldwater headache like the hardest helmet in the Shogun's army.
2MM Geoprene recommended for cold water temperatures of 52°-59°F
