Only Sterling ropes have DryCore. DryCore is just that - dry cores. The core is the strength and power of your rope. A wet rope is not fun, not only does it become heavy and cumbersome, but more importantly and less obviously, your rope will lose that critical strength and stretch may increase. Even if you dry treat your rope, the effects of abrasion and use will lessen its effectiveness over time.

This won't happen with Sterling's DryCore because of the proprietary process used to enhance the fiber. Since the core represents about 70% or more of the weight of the rope, almost three quarters of your Sterling rope is ALWAYS dry. This is a unique safety feature that only Sterling offers. With DryCore, your rope will maintain its superior stretch and strength characteristics.
