Mutant 4/3mm Chest Zip w/Hood

Our Take: 

The Mutant is the best 4/3 for the weird New England shoulder seasons. The removeable hood keeps you from freezing in November and from sweating in May, and its rubber is durable enough to last multiple years of light use in the shoulder seasons. 

What They Say:

Accept no limitations. O'Neill's exclusive Modular Closure system with new dual cinch on the neck and hood closures seal out water. The Mutant is constructed of UltraFlex neoprene making it more flexible and Technobutter Firewall to keep your core warm enough to perform.
