Quality and performance are the two most integral features of our products, which is why we have reintroduced the proven S series and C series wings with key improvements. New materials include a 1680D Cordura for the exterior bladder and 420 nylon for the internal bladder. The LX design also includes a 360 degree internal retraction system. This has been added to match the design of the wing, allowing for a streamlined rig at all times. We have also added a new oval corrugated hose, redesigned OPV and stainless grommets to replace the mesh on the bottom of the wing. Every new LX wing includes a lifetime warranty.
