ULTRA 400 Black Magic (Half-Yard)
$23.00
Ultra400X – 400d Ultra-PE is about 20% lighter, with four times the abrasion resistance of other 400d U-PE fabrics. A great all-purpose high modulus pack fabric.
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.

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.
