What Our Gearhead(R) Experts Are Saying: "This wetsuit keeps young surfers warm and flexible in chilly water without feeling heavy. The Thermal Smoothie chest and back panels make a big difference against wind, and the ankle zips and back entry make it easy for kids to gear up on their own." Cold water doesn't stand a chance against the Roxy 4/3mm Prologue Back Zip GBS Wetsuit. Designed for warmth, durability, and freedom of movement, this cold-water steamer combines FreeMax super-stretch neoprene with wind-blocking Thermal Smoothie panels at the chest and back.

Bluesign(R) certified Hyperstretch 3. 0 panels in the arms and legs ensure easy paddling and unrestricted mobility. The Hydrowrap neck closure and triple GBS seams lock out cold water, while Supratex knee pads add flexible protection during wipeouts and kneeling. Finished with a full back zip and convenient ankle zips for effortless entry, the Prologue 4/3 brings lasting warmth and reliable comfort to every session.
