CST ILCA and Laser tiller extensions have been the preferred choice of Olympic and World Champions over the years, due to their lightness, durability, stiffness and design. Their trademark aramid fibre weave not only looks good but serves a purpose.
The final layer is an open-weave, spiral helix in aramid (Kevlar) fibre which further improves damage tolerance and grip. It also aids to keep the extension in one piece even if the extension gets caught between two boats and breaks.
