Description The Challenge ULTRA™ line of fabrics is composed of the highest performing UHMWPE composite fabrics in the world. In a class of its own, ULTRA™ represents a new paradigm in durability and weight. ULTRA™ weave is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to our revolutionary Challenge RUV™ film. The result is a textile that is incredibly strong, lightweight, and waterproof to 200 psi. ULTRA™ performs in the harshest environments, in both sub-zero and tropical climates. Challenge ULTRA™ is the ultimate in ultralight pack fabric, with the strength to go the distance in the most demanding backpacks and duffels. Our woven ULTRA™ line, ranging from 100d to 800d, is elevating adventure sports to the next level. Ultra800X – Doubling the denier of 400d gives Ultra800X the strength to go the distance in the most demanding packs and duffels. UHMWPE Ultra High Molecular Weight Polyethylene UHMWPE fibers are the lightest and strongest fibers commercially available, with a tensile strength 15x stronger than steel. UHMWPE 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. *All Specs are estimates and may vary from color to color and batch to batch.
