Narrow dyneema slings in 11mm Dynatec tape from DMM.
These are much lighter than standard nylon slings, and quite a bit lighter than most manufacturer's 12mm slings, but are still rated at over 2 Tonnes (22kN). The downside is that they do not wear as well as Nylon Slings and so will not last as long.
Perfect for threads and thin cracks behind flakes. Colours as stated but please be aware that when DMM say "Red" they actually mean a very browny sort of red, though confusingly sometimes they mean scarlet!
