You've probably seen the Edelweiss Curve 9. 8mm Dry Unicore Climbing Rope at some sport crag, faraway alpine wall, or even the gym. That's because most climbers can agree on this best-selling rope's versatile 9. 8mm diameter that's both friendly for beginning belayers and light for advanced climbers working on projects. Edelweiss treated this Curve with a Dry treatment to add dirt- and water-resistance, and the Unicore construction connects the core to the sheath to eliminate sheath slippage for long-lasting use. The HD Cover sheath has a smooth braiding process that you can actually feel. This climbing rope's durability and lightness enters it into Edelweiss's most advanced generation of climbing ropes.
