The Sub Xero by JS Industries is part of the new 2021 range. It is a modern twist on the popular Psycho Nitro. JS has slightly removed foam under the chest. They have also added more area to the tail and gave it a straighter outline. This board provides a fast reactive feel from the swallow tail, while still allowing for pivot and acceleration in average conditions. This all-round surfboard has a smooth rocker outline and low entry rocker makes the perfect combination for a Summer addition to the quiver. It's all about plenty of speed in smaller waves.
