Unparalleled Durability. As opposed to traditional rubber resistance tubing, XD™ Kevlar® CoverCords™ are made with a special Kevlar®/ Nylon sheathing that provides three huge benefits:
-Built-in stretch limit where the user cannot overstretch the rubber tubing inside.
-Ultimate protection for the user. If the tubing inside the sheath were to ever become compromised the breakage would be contained by the ultra-durable sheath.
-Superior product longevity. The sheath protects the inner tubing from the elements that cause rubber to wear outand break over time. No need to replace these year-after-year.
5 Levels of Resistance available for users of all levels. Each resistance level is silicone labeled with color for easy permanent identification. Cords are made with high-quality rubber over-molded handles for superior grip and comfort. Full set includes one of each resistance levels (X-Light to X-Heavy)
