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 Hanzō blade. But it will block a coldwater headache like the hardest helmet in the Shogun’s army.

Most neoprene is petroleum-based. It's messy, it's hazardous - it goops up sea otters. Matuse's wetsuits are made from Yamamoto rubber, which is derived from 99.7% pure limestone. It is warmer (98% water impermeable) and lasts longer (titanium coated) than standard neoprene. It is also kinder to mother nature since it's made from limestone and does not come from petroleum. Yamamoto's Geoprene technology means thinner rubber is warmer rubber. It not only weighs less, it also allows athletes to focus on the right issues (like better surfing), and fuss less over the wrong ones (like being cold, uncomfortable - and performing like a wet noodle).

Features:

• Glued and blind stitched seams.
• Titanium-coated SCS on upper body prevents evaporative heat loss.
