New Dyneema® Woven Composites feature a dual-layer structure of Dyneema® core with a 100% fully woven Dyneema® face fabric. New backpacks from Hyperlite Mountain Gear are the first products on the market to feature this game-changing technology and are available to consumers and outdoor enthusiasts worldwide starting July 15, 2025.
GREENVILLE, N.C. – July 14, 2025 – Dyneema®, owned by Avient Corporation, an innovator of materials solutions, has once again pushed the boundaries of fabric engineering — this time by increasing the Dyneema® layers in its latest advanced composite fabric material. These new Dyneema® Woven Composites take material performance to the next level by combining the unmatched strength of a Dyneema® composite core with a 100% Dyneema® abrasion-resistant woven face fabric.
This next-generation composite fabric material can offer up to 10 times more abrasion resistance, 5 times better tear resistance, and 34% weight savings compared to the existing Dyneema® high-performance composite portfolio.
Fifteen times stronger than steel yet light enough to float on water, Dyneema® is the original ultra-high-molecular-weight polyethylene (UHMWPE) fiber, which is trusted in countless applications where performance is paramount and reliability is critical.
The secret is in the science. Dyneema® Woven Composites feature a dual-layer composite structure that combines the strength, abrasion resistance, and durability of a fully woven Dyneema® face fabric with the dimensional stability, structural integrity, and lightweight waterproof properties of Dyneema® composite technology. The result is a fabric that is highly durable under significant load conditions and after prolonged use.
“Dyneema® Woven Composites are a major breakthrough in materials engineering,” said Chiharu Pidgeon, Global Business Manager, Fabrics & Composites for Dyneema®, Avient. “By harnessing the full potential of Dyneema® fiber with precision-layered construction, we’ve created a fabric that doesn’t just resist wear – it redefines strength and stability in high-performance applications.”
Dyneema® R&D specialists spent two years extensively testing the new fabric with longtime collaborator, Hyperlite Mountain Gear, a leading outdoor gear manufacturer. With the help of Hyperlite’s extensive network of elite athletes and mountaineers, they tested prototype backpacks during months-long expeditions on some of the most extreme hiking trails from the Alaskan wilderness to the summit of the Rockies and beyond. The consensus was clear: the world’s strongest fiber™ just got stronger. Backpacks from Hyperlite are the first products on the market to feature this game-changing technology and are available to consumers and outdoor enthusiasts worldwide starting July 15, 2025.
This innovation pushes fabric engineering to new heights, delivering a composite that can withstand some of the most extreme and demanding environments, reinforcing Dyneema® as the global leader in fiber technology.
