Calamine 11.7mm from Yale Cordage has a NYLON CORE & POLYESTER SHEATH
This pink and purple combination is CE Approved to CE EN1891 Type A and also meets the minimum ANSI Z133 standard for climbing ropes.
This 24 strand strand polyester cover is tightly over-braided on a nylon core, which makes a flexible, moderately stretchy, spliceable rope for SRT and DRT lovers alike. Probably one of the most versatile Arborist climbing lines of all time. In spectacular colors !
