Xtorm Solid Blue cables are ultra-strong and built to last. Every detail is designed to withstand the wear and tear caused by heavy use. Ultra-strong materials Cables in the Solid Blue series consist of a multi-layer composite that contains woven nylon and DuPont™ Kevlar® fiber. This composite material is what gives the cable its strength and durability. Bend-proof Every Solid Blue cable incorporates XFLEX⁴, a technology that makes sure the connectors at both ends of the cable are bend-proof. This has been tested to the extreme by bending the cable for over 30.000 times, ensuring they are of the highest quality.
