Edelweiss's Excess 9. 6mm EverDry Unicore Climbing Rope is strong enough for sport climbing and light enough for alpine routes. At 9. 6mm, the Excess is an excellent introduction to intermediate climbers looking for something lighter and more supple. Its Unicore construction bonds the sheath to the core for long-lasting durability and better handling. Edelweiss treated this rope's sheath with EverDry for decreased water absorption and enhanced abrasion-resistance, and there's a mid-rope indicator for faster rappel setups.
