Rated 5 out of 5 by from Great, versatile rope w many uses A great rope for the money. It is very versatile for dry and wet conditions. Have used the rope on variable and unknown alpine routes (not as a primary rope for protected vertical climbing though). Also is a great for most snow travel, including Mt Baker and Mt Rainier in WA state. The color is bright making it easily visible on rocks and snow alike. Can be used with another single rope to take bigger falls but strong enough to rap on. The only thing is that it had a tendency to coil up a bit more on glacial travel. Overall, great rope with many abilities if you know where and how to use it. Just note that it is technically a single rope of a double rope system for strenuous vertical climbing.

Rated 5 out of 5 by from Great Value Rope Works great for Rappels. Very secure. Holds knots well. Good amount of stretch. I use it for short rappels and it works fabulously. It's light weight is nice to carry when mountain climbing with an already heavy pack.

Rated 5 out of 5 by from Great for glacier travel This is a great rope for the money. It is lightweight and fun for glacier travel in western WA with some long approaches to climbs. It hasn't sustained a fall yet but I'm confident it will handle it fine.

Rated 5 out of 5 by from 8.4 Sterling ropope I bought the rope prior to climb Torrey's Peak in February and for all feature climbing like Shasta next month. The rope is supper great very light which for me is very important as a mountaineer keeping constant eyes on weight. I also love the way rope bends when you making figure eight or any other nut associated in climbing. 30 m and 8.4 capable to take over 14,000 pounts of weight if necessary it makes this rope perfect for 2 or 3 people glacier travel, my personal opinion. I love the rope.
