The 9.7 Sportster is Esprits work horse cragging rope. Designed to perform better and last longer than any other rope on the market. The Sportster is woven wet which creates a tighter sheath & core and subsequently gives it an amazing ability to roll over edges instead of flattening. This process and their patented style of heat setting combine to create a rope that lasts almost twice as long as any other rope this diameter. Often described as "hard to handle" by newer climbers, the Sportster is a stiff rope with little drag appreciated by seasoned athletes like Conrad Anker and Dean Potter. A bit more expensive but well worth the $. Esprit does not pre-dye their nylon which gives it greater strength. Esprit offers a 100% organic surface dye for a few dollars more for climbers looking for a little color.
