The Couloir is a lightweight climbing rope that can be used in half or twin configuration. It is dry treated to the stringent UIAA standard to resist freezing in cold environments, or soaking up water at seacliff venues. Low impact forces give extra security when falling onto marginal gear like ice screws.
What gives these ropes five stars is their exceptional water repellency and abrasion resistance. They work great in below-freezing temps and for alpine climbing.
