Slings age according to the same principles as rope, since they are produced from materials with very similar ageing behaviour. It is difficult to define their lifetime, since slings are often used differently. Check your sling every so often for signs of damage and use the following criteria to decide whether or not a sling or webbing needs to be replaced;

  • After a hard fall (mechanical damage as the result of frictional heat)
  • If the seam pattern is damaged (doubts in relation to strength)
  • In the event of irreversibly heavy soiling (for example, by grease, bitumen, oil, etc.)
  • After contact with acids, for instance from a car battery
  • After high thermal exposure (melting or signs of melting as a result of contact or frictional heat)

In the end, your own personal feeling of safety will decide when you no longer trust your sling.

 The table below shows guide values for the service life of slings and webbing:

Frequency of useApproximate lifetime
Never usedmaximum 10 years
Rarely used: once or twice a yearup to 7 years
Used occasionally: once a monthup to 5 years
Used regularly: several times a monthup to 3 years
Used frequently: every weekup to 1 year
Used constantly: almost dailyless than 1 year

Care Instructions

After a hard day on the cliffs, slings and webbing are often covered with dirt and dust. To maintain the quality and safety of your slings, you need to clean them regularly.

  • Clean soiled slings in hand-hot water with soap and a small amount of mild detergent, or in a delicates machine cycle at up to 30°C.
  • Rinse in clear water.
  • Leave to dry in the shade.Store slings in a dry, dark and cool place, outside transport containers.
  • Protect them from direct sunlight, chemicals and heat. In particular, avoid contact with chemicals and sources of heat.
  • Aggressive chemicals can significantly reduce the breaking force of webbing while leaving no visible sign of damage. In the event of contact, replace the sling immediately.


Mammut® stitched webbing is an essential component of your personal climbing safety kit. Easily accessible and safe, it is a key part of any climbing harness.

Slings are climbing aids stitched from webbing. The webbing is generally 8-26 mm wide and around 2 mm thick. The two ends of the webbing are placed together and stitched to create a sling. Additional seams can be stitched to create special slings. The basic types are:

Express slings

Small slings with a stitched middle section. Used to link two quickdraw carabiners together. These are connected in the openings at the ends of the sling. An integral rubber ring or protection cap prevents the carabiners from turning. A quickdraw is used to link the climbing rope to a hook in the climbing wall. Mammut quickdraw slings are available in lengths of 10/15/20 cm.


The ends of the webbing are stitched to create a sling. Slings can be used for different applications (connecting two fixed points, placing a sling around a single fixed point, etc.). Mammut slings are available in lengths of between 30 and 240 cm.

Belay slings

The webbing is stitched to create an additional loop. This sling is used for self-belaying on belay. When abseiling, the abseil device can be attached in the additional loop. Mammut belay slings are available in lengths of 65 and 90 cm.

Daisy chain

A sling can be stitched in several places to create a daisy chain. This type of sling has a wide variety of uses for self-belaying and technical climbing due to the countless attachment possibilities. The Mammut daisy chain has a length of 135 cm.

Shock absorber

A sling is stitched with different seams. The shock absorber can be used wherever high fall factors threaten the load capacity of an anchor. The fall factor can be reduced by about 30% by tearing open individual seams when the load exceeds 2.5 kN.
