The 2021 Duotone Evo SLS joins the revolution in the Duotone range and will excite every experienced, ambitious and enthusiastic kiter. SLS stands for Strong Light Superior, it’s the quest for perfection, and it incorporates new technologies, construction materials and techniques everywhere you see the SLS logo. For the 2021 Evo that means Penta TX, a brand new material to replace the Dacron in the kite, it’s considerably lighter and offers up to five times as much tear resistance. This reduces the overall weight and gives you a faster kite that will fly in less wind. In addition to new materials, the kite has been redesigned to maximise the performance opportunities.
