Single Rope Technique (SRT) gear

This equipment is not required until you get into caving seriously.


Any harness will do, but caving harnesses are specifically designed for SRT and are recommended. Considerations are comfort: you may be sitting in the harness for some time;

cleaning: harness will get wet and muddy.
