Mammut made the Magic Sling 12. 0's load-bearing seam disappear so you don't have to worry about aligning the seam safely on climbing anchors and extending climbing protection. This seamless sling also features a UV- and abrasion-resistant sheath that protects the light, skinny Dyneema core from sunlight and sharp edges for long-lasting durability.
The Magic Sling 12.0 has been produced using a completely new method a core of round twisted Dyneema yarn is surrounded by an abrasion-proof sheath. Resulting in an ultra-robust sling without any load-bearing connecting seam. Thanks to its special construction, the Magic Sling 12.0 offers significantly higher knot strength in comparison with conventional webbing slings. The core-sheath construction (load-bearing core and protective sheath) also makes the sling far less susceptible to damaging UV rays, and abrasion from rough rocks does not impair the sling's tensile strength. The Magic Sling 12.0 is suitable for universal use and offers absolute maximum safety. 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.
