The ION Mens Seek Core 5/4mm Back Zip wetsuit offers warmth and protection in the cold season while being durable and stretchy.  The single-lined back panel allows freedom of movement where needed, whilst Hot_Stuff 2.0 provides warmth and quick drying. In spots without thermal lining, super soft Silk_Stuff increases next-to-skin comfort to the max. Highly durable nylon in the leg and torso area make the Seek Core a very robust companion for your adventures. Seek Core Backzip models feature additional protection pads at the shins as well as detachable leg loops to prevent water from rushing into the suit.
