8.6mm Cobra II Unicore 200m Dry
Description
The great classic for adventure climbing.
Light and free-running for ease of use on long routes, on the crag and in the Alps. Technical and robust enough to sustain the most difficult loadings, it is even better today because it now benefits from all the advantages of the UNICORE technology.
This is the multi-use rope par excellence, if you don't want to own more than one double rope, it's the COBRA you must have. It has a low impact force (5,1 kN) to minimise anchor-point loading, and a sheath of sufficient thickness to withstand the most aggressive rock, all for only 48 g and a record number of falls = 16.
STRONG POINTS:
• Excellent compromise between strength and lightness.
• Low impact force and raised number of falls sustained.
• The rope doesn't bunch up and remains supple for the long term.
• Allows escape by abseil even if the sheath is cut.

The Cobras are great ropes, especially if like myself you're looking for a rope that will last and be up to many different days out across the disciplines. I am totally sold on the UNICORE construction, especially for stuff like sea cliff climbing where the chance of cutting through the sheath while abseiling into a crag is something you need to consider. They handle well and over the last few months have withstood repeated days out on rock and snow. The Cobras sell at £121 for 50m and £145 for 60m, which is middle of the road in terms of price - but you'll not be replacing these anywhere near as fast as a cheaper rope, so it's money well spent in my eyes.
