I’ve used this rope in all kinds of terrain so far from alpine ice climbing, long multi-pitch routes, and even cragging. My opinion is the best place for this rope is in the alpine. It flows nicely and with proper management, I had no issue linking pitches to the full rope length of 80m! 


I’ve used the rope so far in a gri gri 2, DMM pivot, BD ATC guide, and the grivel master pro. Across the board, the rope flows smoothly and locks consistently with no slippage in these belay devices. Also noticed no slippage in top-down belay on vertical and traverse pitches.

I’ve mostly had this rope on ice but now that we are moving into rock season I’ve had several days on granite, basalt, limestone, and sandstone. So far the wear is minimal to non-existent. That being said with the thin diameter I wouldn’t use this rope for heavy top rope use or projecting routes. The rope also meets the UIAA standard for dry coating and on the warm wet ice days the rope hasn’t wet out at all.

The verdict

This rope is sick, I would primarily use it on fast and light multi-pitch routes, and alpine climbing. It packs down very nicely and has minimal weight. I’m stoked to get this rope out into the Cascades this summer as it will be my primary alpine cord. If you’re mainly climbing single pitch sport routes and projecting I would look into a beefier rope but this will suffice for that last minute cragging session if needed. I hope this review helps you in choosing your next cord! Send and return! Price as tested $299 on
