When the water gets cold, the core get after it.
Mother Nature has a pretty sadistic sense of humor, so she makes sure to align perfect waves with icy water, just to mess with you. The joke''s on her, though, because O''Neill''s PsychoTech 4/3 Men''s Hooded Wetsuit makes it easy to shred chilly waves with its combination of warm and flexible neoprenes, high-tech features, and seriously watertight design that prevents flushing and freezing.

Seeing as it''s one of O''Neill''s top-shelf cold-water suit, the PsychoTech employs two of the company''s finest neoprenes, TechnoButter 2 and TechnoButter 2 Air Firewall. The latter, a super warm and flexible material, makes up the majority of the torso to keep you comfortable in cold water, while the former is lighter and stretchier to provide unlimited mobility in the arms, legs, and shoulders.
