The top-notch pick for cold water sessions with premium materials for ultimate heat & optimum stretch. The Seek Select 4/3 Back Zip comes with Graphene lining - an incredible heat conductor that makes sure you stay warm on the water. Only high-quality materials were used to make the Seek Select the most progressive wetsuit line without compromises. A minimalistic panel design allows for limitless freedom of movement while sealed seams prolong the lifetime. Made to explore the toughest conditions, ION added Graphene_Plush throughout the torso and legs. Hot_Stuff 2.0 lining provides additional warmth to the arms and shoulders. To increase flexibility and comfort in this crucial area, ION uses Max_Flex, a new rhombus-shaped outside lining for unparalled stretch. Seek Select Backzip models feature additional protection pads at the shins.
