The CAMP USA Genius 9. 0 Dry is built for the objectives where the rope is one of the heaviest things in the pack: long alpine routes, remote multi-pitch lines, and big days where the system needs to flex as the terrain changes. The dry treatment keeps moisture from adding to pack weight when conditions turn wet, and the triple certification covering single, half, and twin means one rope covers the full range of systems a technical mountain objective might demand. What Our Gearhead(R) Experts Are Saying:"Triple-rated at 9. 0mm, this rope lets me run a single-strand system on the approach and switch to half-rope technique on the technical terrain without swapping gear."
