Not only has the Pioneer seen the introduction of the new Aquatexx EV®, but the additional Skull Caps have also seen a rise in technological advancements as well, featuring Aquatexx EV® to represent the utmost in contemporary shelter materials and a hydrostatic head of 25,000mm, far surpassing anything else on the market.
