Key Benefits

Ultra durable
15 times stronger than steel by weight, Spectra® technology enhances our most pinnacle products with unparalleled durability and longevity.

Abrasion-resistant
Made with a patented gel-spinning process, Spectra® yarns are ultra-strong adding robust protection against rips and tears when woven into a product.

Lightweight
Despite its exceptional strength and durability, Spectra® is light enough to float, creating high performance products that won’t hold you back.
15 times stronger than steel by weight.
Also used in space exploration and body armour, Spectra® provides enhanced protection, durability and longevity without sacrificing performance. Made using a patented gel-spinning process, Spectra® is 15 times stronger than steel by weight yet light enough to float. These ultra-strong yarns can be woven into fabrics to create an enhanced product that is ultra-durable yet lightweight and UV-resistant so it maintains its strength even at high altitude.
Patented Construction
Made using a patented gel-spinning process, Spectra® is an ultra-high molecular weight polyethylene fibre with a very high strength-to-weight ratio.
Trusted Durability
Ultra-strong yarns are wrapped in nylon and woven into products in a gridded pattern to provide exceptional abrasion-resistance and long-lasting durability.
