A superb specialist fully dry-treated rope that is ideal for winter climbing, alpine style ascents and expedition use. Excellent longevity and handling. 50m
Unicore is a process that bonds the sheath to the core in such away that if the sheath is cut or damaged there'll be no bunching up when abseiling, ascending or belaying. This means that you get zero sheath slippage.
NB This a 'Half Rope' and should be used in conjunction with another Half Rope. Confusingly these are also sometimes known as 'Double Ropes'.
Having said that, people often use Half Ropes singly, particularly in 25m and 30m lengths, for scrambling (to protect the second, not the leader) and for glacier travel where a fall is likely to be more of a slither. These are situations for which there are no official tests and individual judgement must be used.
Price is per rope, not per pair.
