Developed in partnership with Challenge Sailcloth, this unique Ultra PE leading edge and strut composite material is 25% lighter and 10x stronger than traditional fabrics. This allows for 50% higher pressure, creating increased stiffness combined with a thinner leading edge. The result is supercharged responsiveness coupled with sublime handling, and of course the long-term performance you expect from Airush. 

UHMWPE fibers (non-branded Dyneema® or Spectra®) are the lightest and strongest fibers commercially available, with a tensile strength 15x stronger than steel. UHWMPE is created by a gel-spun extrusion process which draws out extremely long chains of polyethylene, aligned along a molecular backbone. This alignment effectively transfers load through the fiber for high modulus and strength.
