Our cord is Poly sheath and Poly core, and absorbs quite a bit less water than nylon cords. It is also quite a bit more static, so you won't need to fight the stretch. Works better! After using a very pretty but very stretchy nylon accessory cord as pull cord for a couple of years, I figured it was time to make some 100% Polyester pull cord for superior performance.
Weight: 2 lbs, 0.5 ounces (per 100 feet)
Strength: about 2200 lbs. This cord is meant to be used as a PULL CORD only. Do not rappel on this stuff - it is not strong enough for that. Wear a helmet, be careful out there.
