Jonathan Whitewrote a review of Mammut Serenity Dry Climbing Rope - 8.7mm on November 10, 2016
Familiarity: I've used it several times
I took this rope on a 4 pitch mixed ice route on Mt Spalding. I wanted a light packable rope since the approach was around 7 miles and the climb tops out at 13,500 ft. This rope combined with ultralight cams and a light rack of screws allowed us to keep our packs around 25lbs for the approach. It snowed while we were climbing and the rope stayed dry.
I used a Petzl Reverso 4 with this rope as I have had braking issues with skinny ropes and my ATC guide. Reverso 4 worked great with this rope.
Rope is supple
Did not kink or tangle
A bi-pattern would be awesome
