The Sterling Evolution Helix is a skinny workhorse rope that hits the perfect sweet spot between light weight and great durability. We think it is one of the best ropes we have used for almost any type of climbing.

In my opinion, the best multi-pitch rope out there is Sterling’s 9.5mm Evolution Helix. The Helix, and it’s smaller sister the 9.2mm Aero both have some unique qualities that set them apart from anything else on the market and make them our go-to ropes for multi-pitch adventures. I’ll break them down into the qualities I mentioned above; durability, light weight and hand.
