The top-notch pick for cold water sessions with premium materials for ultimate heat & optimum stretch. The ION Seek Select 5/4 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 unparalleled stretch. Seek Select Backzip models feature additional protection pads at the shins.
