Slings are an essential part of any climber’s kit and are available in different lengths and widths to accommodate their many uses. The webbing loops are usually made of Dyneema or Nylon; the former is thinner, lighter, more flexible and often favoured for climbing while the latter is a more traditional (and usually cheaper) option. Dyneema slings are available from 8mm to 12mm in width while the Nylon slings are 16mm in width.
